Labug told me to check out your posts. I've read through a few and it seems that our sitch's are quite similar. I have a 2 and 3 year old and I'm 13 weeks pregnant.
H dropped the bomb that he had been having an A for 6 months in November and had, in fact, had multiple in the first 3 years of our M. He has broken it off w/ OW, but wasnt willing to give me transparency, so I told him my boundries or we needed to S. We have been S for almost a week. It is considered temporary by both of us, thought, we both know it could end of permanant. We both feel this is more of a step to saving our M than to continue to live together. I can' t just move on and pretend everything is fine, which is kind of what he wanted me to do...but knew I couldn't. Then he got mad at himself for even telling me about the As. At first, he thought we was done and would D. He is very sick and confused.
I too, have things I do need to work on and own for the state of my M in the year or so leading up to this last A. Lots of similarities there. I really changed after having kids. They became my focus, and our R wasn't as important. I am not the best listener and can be quite controlling. (my mom is super controlling, and having kids brought that out in me) I will just take over and do everything for you, if I love you. Not the best thing to do. Ha. All things I am actively working on and have made alot of progress on.
Anyway, I was also a SAHM for the first 3 years and started working 2 days a week last year. So I have the kids Sunday-friday and H will take them on the weekends. They really don't get what is going on yet.
I really feel for you! I'm also glad to see someone who has a similar sitch as mine, as far as having such young children and being pregnant...ahhhh.
