Anyone every have a break up with someone they really loved and end up sleeping with some else and accidentally and surprisingly get pregnant ?

Please don’t judge me! I was in a relationship with someone I believe I still love. I couldn’t deal with the emotional neglect , the lies, cheating on me because he claims he had a sex addictions and with women at massage parlors ?? !! We have a son together and he cheated on me when I was carrying him too. He really hurt me. After a while we broke up and I was so angry that I was the only one really trying to hold our family together.

I felt stupid. Betrayed. Used. Broken and many others from his treatment. Eventually, when I was single, about 2 months after we broke up, I was spending time with someone that was treating me the total opposite. He gave me Somethings I seemed and needed from my ex . One thing led to another and we slept together one time and well..... I got pregnant.

The other guy knows and he is supportive now but was very confused in the beginning and even doubtful because it was so fast and we thought we were being careful enough. He believes now that he really is the sad and is accepting of it.

A part of me doesn’t want my ex to know but I know it can’t be hidden because We have a son together. We also have 5 years together and all those years I didn’t feel love or maybe he just didn’t know how to show it. I honestly don’t want and was not prepared for another baby now, but I can’t see myself aborting my own child. I feel like my ex will cal me all kinds of names and even hate me. Even though we broke up for a short time. We are still not together and fight all the time because of our son and miscommunication.

I don’t know what think or do. Or how to teach myself to leave it alone and deal with it. Anyone experience this ?
