Long story short: he had an affair in 2020, we've stayed in contact the whole time (please don't yell or lecture me; I know); he told me it was his biggest regret, he loves me, he wants to be with me, etc. I knew it wasn't completely true or he would have made actual moves to be with me but I wasn't ready to let go (still not ready).
The affair relationship didn't last long and we've had nice times since then. But then in September I found out he was spending a lot of time at a place that wasn't his. When confronted, he said it was a friend - it was totally platonic, etc. I wasn't born yesterday and didn't believe that and he swore I'd meet her - but then I found out who it actually was and he admitted they were casually dating.
Then he changed the story to the romantic part of it was over and it was just a friendship again. Only for me to find out on NYE that, no, it's a real relationship (I mean, I knew that but now I had proof) and that she actually was with him and his family for Christmas.
This doesn't feel like the affair did - this feels like a real relationship and he spends tons of time with her and obviously loves her. I just feel deep certainty in my gut that, not only will they last, she'll get everything I wanted - a good marriage, kids, loyalty.
I know people don't tend to change unless they work on themselves but I really think he's going to be true to her. I know he hasn't really been so far - as of Friday he said he wanted to be with me and he's been telling me he loves me their whole relationship - but now that I know, he's gone totally cold on me and distant. I know part of it is shame - but I think that shame is why he'll be a good partner for her. He's not going to cause someone else this pain.
My therapist is a good therapist and won't back up my hopes that he will lie to her, too. And part of me is glad to finally have this closure - but I'm so upset that he can drop me like this and go be happy with someone new when I'm alone. I was the faithful one! Well past when I should have been loyal, I was. I love him - I shouldn't, but I do, and I thought he had some feelings for me that would have meant he couldn't do this again.
Why does he get a happy ending? Introducing her to his family is major. That's why I'm so sure it's going to work out for them. I don't understand what I did to deserve this. And I am certain there's no one else out there for me. It's not fair. I want to know they'll fail but I also feel badly for hoping that - she's done nothing wrong and seems like a fine person from the very limited info I have.
I just feel so unlovable - and I keep blaming myself for all the times I was insecure or even unkind in our relationship - I didn't deserve to be cheated on but I'm sure she's wonderful and doesn't have my issues so he just will never feel the need to betray her. But if he never cheats again, I was the problem. How does anyone cope with that? I can't cope with that. This man told me I was everything to him and he threw me away, twice. How can anyone recover from that? I can't.
Please don't tell me to block him, divorce him, etc. I know all that and my situation is tricky with a divorce. I just need to know I'm not alone. I feel very, very alone.
