My (25F) ex-fiancé (25M) took my ex-best friend’s (25F) virginity and moved her into our home.

We were together for 5 years, and I’ve known my ex-best friend ‘Anna’ since we were 4.

I’ve always suspected my ex-fiancé had a thing for Anna. I think if I hadn’t asked him out first, he would’ve asked her out at some point. Anna is incredibly shy and introverted, so my ex used to go out of his way to be nice to her and include her in things. Even when it wasn’t necessary. It used to annoy me sometimes, but everyone convinced me he was just a nice guy and Anna always assured me she would never go there.

I’ve felt insecure our entire relationship over it, and it led me to do something really stupid. I had an affair with Anna’s now ex-boyfriend ‘Jack’. It started 3 months after they started dating and lasted 2 years. It was only supposed to be a one-time thing but every time my ex was overly close to Anna, I went back to Jack. He was in it because Anna wanted to wait until marriage and wouldn’t sleep with him. Also, I suspect he liked having something over my ex. Jack was the only person my ex was never nice too.

Everything came out 3 months ago. My ex had a lot of evidence so I couldn’t even deny it. He moved Anna into our home and kicked me out the same day. He understandably wouldn’t talk to me at all for over a month and neither would she.

I found out I was pregnant a month later, and my parents had to get in touch with his to arrange a meeting because he had blocked me on everything.

Jack has been desperately trying to get Anna back and she told him she had slept with my ex, and he told me. I’m so beyond crushed. I don’t know what to do now. After I found out I was pregnant my ex was giving me hints that he was willing to fix things between us. I can’t believe they would both do this to me. I don’t even get it. Anna was so determined to wait until marriage but the minute she got the chance, she spread her legs for my ex. I feel like all of my insecurities and suspicions have been confirmed. I don’t know how I’m going to co-parent with my ex now. My parents have told me to shut up and pray he takes me back because I can’t live with them forever.

I just don’t know what to do and could use some advice on where to go from here.

TL;DR – I cheated on my ex-fiancé with my best friend’s bf. After everything got exposed, I found out I was pregnant. My ex was giving hints that he was willing to work things out between us, but I’ve found out he took my ex-friend’s virginity and that she is still living in our home.
