Well she made the statement that everyone wants to know if I'm cheating on her since I just come and go. I ask who everyone is, and don't get an answer. One of the few good questions I actually ask.
This is projection. She's cheating on you, therefore she's accusing you of cheating on her. Straight from the wayward handbook. It doesn't really matter who "everyone" is because it's all in her mind. Since you're going out and "being sneaky," it's OK for her to do the same. Except that she's not being innocent and has developed feelings for another man... that she enjoys spending the entire night with while you stay home with your child. You're a live-in babysitter for her! Plus, you go out of your way to make her feel good about herself... and you'll even treat her for her birthday!! But you won't wish her happy mother's day... so confusing! This is why playing these games aren't helping to fix anything with your marriage. It's certainly not helping you to become someone only a fool would leave. Simply pushing her further and further away.
