Jimbo I am very experienced in this area, as I have been married and divorced 4 times! (including married and divorced the same woman twice - actually "just" three different women).
In the process I have "taken away" a woman from her husband, and had one "taken away" from me. Actually, IMO you don't really break anyone up or "take them away" - they just do what the hell they want to do, whichever way it works. Either way, its a SHITLOAD of grief all around. And Confucius is right, too. The woman I "took away" from her old hubby, ended up being the one that ran off with my buddy. As it turned out, it was really his lose and my gain (except we had kids) - she did the same thing to him, further proving Confucius (and Kaotik) right (and in retrospect was a raving bitch with big tits).
One thing I have also learned as a really old guy is that people will sometimes ask for advice and then do whatever they wanted to do in the first place, especially where the opposite sex is concened, but my "advice" is FORGET HER AND FIND SOME OTHER WOMAN.
