I read your sitch and follow closely. I have so much to say, but really can't get it out.
I mentioned my ex began cheating when I ws pregnant and left me when she was 6 months old. He lied to me and said there was no OW. Just blamed it on me. I found out about OW 6 weeks after BD. I found out the cheating began when I was pregnant not until we were already divorced and they were engaged.
When a man leaves their wife and newborn child, there is clearly something wrong with THEM. Honestly, it's a sick thing to do. My dad and stepmother still want to kill him to this day for that and can barely look at him. I did what you did. I thought I must have been so horrible for him to do that.
Well, I began to realize it wasn't me. It's him. I was just so devastated. We had our IVF baby, began our family, and he left. I thought my life was beginning and it felt like it was ending. I would have done anything to just come home. I couldn't envision life as a single mother sharing holidays.
But that's what happened. I survived it. I know it ws the best thing to happen if he wasn't going to change. I don't want who he is. He was never a good guy, that's where my sitch is different, but I mourned the death of the life I envisioned. It's difficult but it was no necessary.
I am not saying your sitch is going to end like mine. There was a poster who had her H cheat when she was pregnant with her first, they were headed towards divorce.....they reconciled and she just had her 3rd kid a few days ago.
My point being, you will be better than ok and better than although it may not seem like it now. But I can guarantee being with the man he is now, you will not be ok And that's on him. Not YOU.
