So confused

I left my husband 10 months ago for another man. Yes. I know that’s awful and wrong. My husband and I had had issues for about 3 years. We went to couples therapy (3 separate therapists) and I went to therapy on my own as well. He became pretty verbally abusive towards my kids as well (they’re 18 and 16 now) so that made me even hate him more. We have a 4 year old together and thankfully during our separation - even after knowing I was leaving for someone else - he was pretty civil. I left the man I had left my husband for about a month ago. I’m still mourning that loss but I was then faced with the prospect of “dating” and that frightened me to the core. Specially because of my 4 year old. I know that if my relationship is to progress with someone new I’d have to eventually introduce them to her and I honestly don’t want to. I’m only 35 so I’m definitely not thinking about single life for the rest of my life. My husband continued therapy on his own, has read many self help books, and took 10 coparenting classes. He’s doing what he must go get himself in a better state and he’s very excited at the thought of him and I reconciling. He really wants us to work it out. For us and for our 4 year old. I told him yes so we have seen each other on the weekend and we are going to continue living apart with the custody arrangements we have in place. Does it sound like a bad idea?
