My wife (f25) and I (M26) have been together for almost 6 years. Last March (2023) she met someone (f29) at a bar a week before our wedding . They kicked things off by flirting with each other a lot . My wife and I have had conversations about having a threesome but never went out of our way to make it happen. Fast forward to a couple months later and my wife and her are hanging out almost all the time , one night my wife suggests we have her over for drinks . I agreed and one thing led to another and we had our first threesome , we end up hooking up with her 4 more times but out of nowhere the sex just stops and she was just coming over and hanging out around the house . I didn’t mind as I thought it was cool having someone else around the house . She stayed over a lot to the point she was pretty much living with us . She ends up asking us out as a throuple, my wife and I not knowing much about it had asked her for time to think about it as we were new to the whole idea. My wife and I had a long conversation about it but decided to give it a go and said yes. The next couple of months were great . We were open about it so our friends knew about us , we went out in public a lot and had cute dates all three of us . Even had one on one time between us all. It was perfect, but out of nowhere came our last day together. Nothing felt weird and it caught both me and my wife by surprise. We had went out to eat to a restaurant she suggested and then we went for a walk in downtown area. The night went well but the following day we don’t hear from her at all. She texts my wife later that day breaking up with us, her excuse was that she needed to work on herself and her relationship with God. Understandable, I guess…. A couple DAYS later my best friend shows me a screenshot of her asking him to hook up at 2am… thankfully he didn’t answer/ entertain her but it hurt , I didn’t know how I was supposed to feel about that and just pretended like I didn’t care. I told my wife and of course she’s hurt and becomes a bit depressed over the situation. By this time it’s early June (2024) my wife and I talk about it and reminded each other that we had each other . We chose to move on and by July we were about to hook up with someone new but decided not to . By August we went on 2 dates with someone else but didn’t really feel any true chemistry. We decided to stop rushing and if and when we meet someone then we’ll know. About 2 weeks ago we ran into her (f29) at a bar. We didn’t talk to her and headed out shortly after we seen her . That same night my wife decides to snoop through her instagram and sees she’s in a mfm relationship, this was confirmed by a mutual friend of ours we asked . I thought I was over it but honestly I’m more hurt now. It sucks even more because I never treated her wrong and it feels like she hates me. When she broke up with us she texted my wife, didn’t give me any personal closure. She also stayed in touch with my wife a couple days after the break up making sure she was okay. Also she goes after my best friend and has me blocked on all her socials but not my wife. I thought we had a genuine connection but I guess not. I guess my question is how can you get over a breakup like this ? And why do I feel so alone even though I have such a loving wife ..
