Sorry you are having a hard time. My dh is nicer then ever too and is constantly telling me I am throwing away my kids and he can't believe I don't want to spend family time?? Well, we had 11 years to create family time and you were in the basement passed out or out with your buddies drinking. I am spending family time the same way I always have - with my kids. Sorry if you suddenly want to be included now that we are 2 steps away from divorce!
I have zero desire for a relationship right now so I'm not thinking about it but don't worry - I'm 40yo with 2 toddlers and two grade schoolers so you aren't the only one in that boat!
