Hi, not sure if I've put this in the right place as it's a complicated one but maybe someone can help. Ok so I split up with my son's dad a year ago. He quickly got with someone else but told me he still loved me was gonna leave her blahblahblah... Anyway I fell for it and stupidly have continued sleeping with him for the last year. I recently found out that he has had a baby with her! I had no idea she was pregnant and I would have stopped if I had known but I believed everything he said like a fool and genuinely thought we could be together one day. So since I found out about the baby, he's been begging me to forgive him. Saying it was all a mistake and he didn't tell me because he didn't want to lose me and again I fell for it and in my messed up head I thought I could live with him leaving her in a few months when the baby was a bit older and we could actually have a future. He left her last night, earlier than planned and came running straight to me. Seeing the way he left her and was talking to her I suddenly saw him for what he is. I can't believe I've been so stupid and I'm racked with guilt. To top it all off the girl started messaging me tonight and we've bonded over what a horrible person he is and that our kids are half siblings. She wants to meet up and I feel like we could be friends - except I've been sleeping with her bf through their whole relationship. She's told me about him cheating on me which I didn't know. Should I tell her? Should I befriend her and let our children bond but keep it all quiet? But then what if she finds out another way? Should I keep my distance despite this potential relationship between our children? Please help someone - and please no nasty messages I feel very guilty and I really loved this guy, he's my sons dad and was the love of my life xxx
