Grats to you both, brother. I've been where you're standing now and it was one of the happiest and secure moments in my life.
Best advice I can give is to set time aside each day, no matter how hectic and busy and fucked up life might be at that moment, always take a set amount of time each day to be there in a moment with your partner with ZERO interruptions and distractions. Phones off, TV's off, kids-eventually-bribed with some food or toy to be occupied for 10min.
Take that time and be in that moment with your partner, share with them the things you love most about them, the times during the day you thought of them and smiled, the memories you still laugh out loud about.
Life is a hectic scramble work, meals, training, sex, sleep, meals, etc.
It's easy to get caught up in it all.
But at the end of the day, nothing is more important now than that person playing on your team. You two have each other's backs. So keep that bond solid and strong.
Best of luck to you both.
You look great together!
