I think my marriage is over. About three months ago my best friend, whom I've known for six years, was staying with me and my husband. He and I have been together for three years. Let's call him Jack and her Marla. Jack and Marla have known each other for ten years. Marla introduced us. They were co-workers for a couple years. Marla was married then and is now divorced. Marla lives several states away now and was in town for a visit. We were all hanging out, watching TV and drinking one night when things got out of hand. There had been zero discussion of a threesome before hand; it just sort of happened. It was an awful decision made with three drunk brains. Marla and I were definitely the initiators. The threesome was fun until the end when my husband finished inside Marla. I immediately felt this horrible sense of betrayal. My husband and I have been trying to conceive...not that I was expecting to get pregnant during the threesome but still...I feel like in general a man finishing inside of a woman is an intensely intimate act. Marla left a few days later. For the rest of her visit we joked about it once or twice but then we kind of just pretended it hadn't happened. Jack and I have been trying to deal with the fallout of it all. He feels awful, of course, and has apologized endlessly. But I can't shake that feeling of betrayal. We were going to go to counseling. We have an appointment next week. But now I can't fathom moving forward with that. Marla's pregnant. She called me two days ago, crying. She says she's thought and thought and thought and she just can't have an abortion. She said she wanted to and was going to but just couldn't bring herself to. I don't think I said much to her and when I hung up I cried for hours. I'm beyond devastated. I've been trying to have a baby with my husband and in one stupid mistake of a moment he knocks up my best friend instead. I'm completely shattered. Jack is wrecked. I know we made this mistake together but I don't think I can maintain a relationship with him after this. He's told me that he'll never see the child, he'll sign away parental rights, or he'll be a child support only kind of father but how can I ask him to never know his child? And even if I could, I don't think I could have a baby with him knowing that our child has a half-sibling out there conceived by my husband and my best friend. It feels so pointless. No one did anything wrong. No one cheated or fell out of love. But is our marriage over anyway? Is that right? I love Jack more than anything and I know he'd cut off his right arm to go back in time and change what happened. But he can't. Should I make myself go to the counseling appointment? Is there any hope here? I've never felt more devastated in my life. TL;DR- My husband and I have a threesome with my best friend and now she's pregnant. Can my marriage survive this?
