Has anyone been this situation?

I was with my ex from 18-30 and now 35. We broke up after him being in the street and other things. We have a teenager. During the 5 years I have gotten married and had a baby. Well my husband currently going through a divorce was not who I thought he was and this was revealed after the marriage. My ex is wanting to get back with me and says he’ll accept my youngest who isn’t his but he also says he wants to have another baby by me.

Has anyone else been in this situation and if so how was the outcome?

I actually cheated on him when he got incarcerated after he admitted to cheating on me over the years. I just did more with getting pregnant. But I figure I cheated and got pregnant minus as well get married cause he’s not going to want me back but it appears differently.
