My opinion may not be the most popular, but it's based on my personal experience. Actions speak louder than words. You moved out. 6 months ago. That's half a year. My youngest child was still in the womb when you moved out, and now he says "mama" and eats food.
You often know what is best for you even though it wouldn't have been one of your top 50 choices.
I was divorced when I was 25. My husband and I had been together since we were 17. We had a huge fight one night and I left. I stayed with my parents for 2 weeks. I came back, went to marriage counseling, but it was over. And I later realized, that once someone has reached the point where they are really willing to walk out that door, it's over. You still might not WANT it to be over, but it is.
I'm not saying I got over it overnight. Actually, I instituted NC, and it still took 2 1/2 years. We're casual acquaintences now, but only in the last year or so. We didn't have kids together, but I was pregnant the night I walked out on him and later miscarried.
I know you probably want a two parent family for your kids, and you probably want the infidelity to never have happened. But that's not what R is. R isn't everyone pretending the infidelity never happened. It's in your face day after day for the rest of your stinking life. Some days I have no idea what the point is. Really.
I didn't leave my WH on Dday for a lot of reasons, but the big one is that I learned the first time around that once someone leaves, it's over. There are some people who will tell you "we got back together..." and they did, and there are happy people who've done that, but it's a minority.
Stay the course. After 6 months, you would know if R was an option, not wonder. one poster here was separated from her husband for 6 months ... he ended the A and went NC from day one, went to AA meetings once or twice a day the entire 6 months, went to IC, apologized to everyone they know...
Is that how your WS is acting?
