Most of that is hogwash. I never cheated on my girl, and I've said/did a lot of those things:
# Unreachable by phone - I'm very busy, but my personal assistant gets all the calls - It's when this is consistently the case
# Unexplained numbers on phone bill - I personally don't know 90% of the numbers on the bill as I speak to so many people - it's numbers that appear frequently
# If you call their cell phone and get the call waiting beep...they say they weren't using the phone. - my cell has broken a number of times - this is a coincidence, you know the chances of a broken cell are pretty slim on the average
# Never leaves the house without their cell phone/pager - I can't. I have to be reachable 24 hours a day. -
# Hang up calls or someone always saying they've got the wrong number when you answer - I always get wrong number calls on all my phones every day-I get maybe 2 a year.
# Acting different( short tempered, distant, defensive, etc.) - numerous other reasons for that. Certainly not cheating. - I agree
# Neglecting chores at home - busy, tired from work - again, when this behavior is continuous
# Picking fights over trivial things in order to get you to leave the house, or so they can leave the house - again, numerous other reasons for that and cheating is not one of them. - again, frequency
# Withdrawing from you/family/friends - stress - stress is one of the biggest reasons for infidelity - not lack of love for the spouse as many think
# Pointing out YOUR flaws - I'm honest. I point the flaws of everyone, but she knows that when I praise her or compliment her (most of the day every day) it's real and sincere. - This would be always pointing out flaws and not complimenting
# Telling you that you'll talk about your relationship concerns when it's more "convenient" - yes, if I am in the middle of an important meeting - If someone wants to talk to you about your relationship when you're in the middle of an important meeting, there IS a problem, but this tip is directed at when there isn't an important meeting.
# Telling you your concerns about the relationship are "all in your head" - of course, if there is nothing wrong, and I am just simply stressed regarding numerous matters, I could seem a bit distant sometimes as I am in my own thoughts. Doesn't meant that I am cheating. - Okay to be distant sometimes, just not healthy when you are consistently or constantly distant.
# The " I love you, but I’m not IN love with you " talk - I said that to a girl once. We just simply grew apart and we were together because it was convenient. I certainly wasn't cheating on her. - I've had this talk with plenty of people too. I wasnt cheating on them, just didn't want to be with them anymore.
# New interest in exercise/diet - maybe I am just concetrating on it more now since I am thinking about a comp, or maybe I have more interest in my cars since I am about to buy a new one, or maybe I have more interest in business since I am starting a new company, etc, etc - yes, these are very excusable. But if a spouse doesn't attend the gym and suddenly want to look like Adonis, and it is combined with more of these items. well....
# More time at the gym - I could just be gettin ready for another comp - absolutely good reason.
# Sleeping ALOT - I am tired! - Also a sign of stress and depression if it is consistent.
# New cologne/perfume - I wanted a change 'cause I got bored of the old one. - Yup.
# New wardrobe - again, I got bored of my clothes or I simply outgrew them. - Yup.
# Suddenly carrying breath fresheners( gum, mints, etc.) with them constantly - I am eating a lot of garlic lately - Yup.
# New password protection on computer - I change the passwords security on computers every few days as standard procedure - Good idea.
# Up on computer to all hours - yeah, it's called work - to earn a living! - Yup.
# Closing dialogue windows on the computer when you walk into the room - I am looking at porn, or looking to buy her another car, or buy her more jewelry or tickets to the opera as a surprise! - Yup.
# Erasing computer history after every use - I do that all the time as standard procedure for safety reasons - Yup.
# Unexplained purchases on credit card - I don't know holf of the purchases on the credit cards - I have over $80k limits and they get used monthly - You really should keep better track of your finances. You wouldn't notice if someone got your credit card and used it??? Not good.
# ATM withdrawals at unusual locations - I travel a lot
# Extra mileage on the car - I travel a lot - Yeah. We all do a lot of that for sure.
# Errands that should take 1/2 hour take much longer - If I am interupted by constant phone calls - Yeah that certainly happens.
# Claims to do things they've never done before ( shop, etc.) - I was trying new experiences - Always good to be open to new experiences.
# Buying expensive flowers or gifts for no reason ( if they've not done that before) - I always do that - If they've not done that before.....
# Leaves early for work or comes home late more - I have a lot of work to do - yup...that sure happens
# Claims to work overtime, yet no overtime on checks - I don't get paid by the hour - Not a problem then.
# Mentioning a "friend" but never introducing you - I have lots of those- they are are all work related and I don't like them on a personal level so Iw oudl certainly not lower my girl so much as to introduce her to these people - If you don't like them on a personal level, you won't mention them as a friend, right?
# Too many visits to "friends" - It's called work - smooching with people to get new contracts signed and deals set up - too many is the operative word here
# Lying about where they've been or whom they are with - maybe I'm organising her a surprise which obviously I don't want her to find out about - As long as there are not "frequent" surprises, this sounds cool.
# Coming home late saying they " just lost track of time" - happens all the time 'cause I am so busy - Do yo do this frequently without calling?
# Offers to go to the store when they usually wouldn't - I am being nice - Again....frequency.
# Sends you to the store when they could easily go themselves - I'm tired or really busy - understandable
# Passenger seat position changes - I always have lots of different people in my cars - I think this is a tip for someone who doesn't
# Changes in sexual behavior with you (may be more or less frequency) or different techniques - I/we like to experiment a lot so yes different stuff is the norm - Us too. It's the norm. Changes in sexual behavior means out of the norm.
# Hiding condoms - I don't want the cleaner to see them - why?
Like I said, most of that is just garbage which will get a lot of people paranoid and will start trouble in their fine relationships for no reason at all.
