Hello there.
As the topic of the message states, I think my wife had an affair with a friend of mine. I believe that it has stopped, but I'm growing more and more certain that it did happen in the past. I'll give a little background:
It all started about three years ago before we were even engaged. At the time, my friend, my wife (girlfriend at the time) would hang out all the time, almost every weekend in fact, with our group of friends. I started to pick up signals back then about him being attracted to her. He'd always go out of his way to compliment her and do whatever he could to help her with anything (carrying things, cleaning up, opening doors, etc.) if I couldn't. I'm aware that this is just gentlemanly behaviour, but he never did this for any of the other women in our social circle. It would bother me, but I suppressed it at the time because I didn't want to come off as being unreasonably jealous. Soon after that, she ended up getting a job downtown, rather close to my friends office. It came up in conversation once that they should do lunch or something, but it didn't seem like a serious proposal at the time, more like an innocent joke. Feeling a little unsure of myself afterward, I asked my wife if she would actually have lunch with him and she laughed and said "no," like the idea was preposterous. I trusted her and forgot about it.
A few months later, our sex life dried up, right out of the blue. We just stopped having sex, and whenever I wanted to be intimate, she was tired, had a headache, wasn't in the mood, etc. It went on for a few months until I asked her what was going on, if she still loved me, or if we were falling back into a friendship. She burst out into tears almost immediately, said that it was all her fault because she's been so busy and "distant," and asked me to forgive her. I wanted to ask if there was another man at the very moment, but I didn't have the courage to, and gave her the benefit of the doubt. Our sex life returned to normal for a few weeks, but the slowly faded again. In fact, it's never been the same. It's the same short routine every time, and whenever I propose doing something new or try to do something new, she refuses/pushes my hand away.
Seeing as how I loved her, regardless, I proposed, and we got engaged. After that happened I saw a lot less of my friend, and when we moved into our house, his attitude toward me became erratic. Sometimes he'd want to come over and hang out, and sometimes he'd be disinterested and borderline insulting.
We got married a year ago, and he was invited to the wedding. I've known him for a long time and know that he loves getting up on the dance floor and having a good time, yet at our wedding he sat at a dinner table the entire time and looked miserable. After the wedding was over, my wife seemed pretty pre-occupied with whether or not he enjoyed himself, asking me if he had a good time or if he said anything about the wedding several times over the following week (we had a delayed honeymoon). Furthermore, when we finally got our wedding pictures posted on our photographer's website, I sent all my friends the link and he said that my wife "looked beautiful, but I'm tired of looking at your ugly mug ."
We barely saw each other or spoke to each other after that, but a few months after getting married I had to go on a business retreat. After getting back my wife was very distant, claiming that she barely slept all weekend and was tired, and then very next morning my friend messaged me online right away and asked how my retreat was. Funny thing is, I don't recall ever telling him I was going.
I hadn't seen him for almost a year after that, until just recently when another friend invited us to a dinner party. My wife and I showed up and discovered when we arrived that he was there, and there was a very awkward tension between them. He outright ignored us for about 20 minutes and then finally said "hi" in a very forced way to my wife, ignoring me almost altogether. The whole thing struck me as an interaction between two people that never planned to see each other again, but were forced to deal with doing so in the company of friends for one evening.
Ever since that night a few weeks ago, my suspicions have been returning and driving me crazy again. Our sex life is still very pathetic, and she always seems uninterested and wants to get it over with, despite us having a ton of fun and doing really creative things before all of this started, and my friend still avoids me.
The thing is, I have no idea if I'm just being paranoid and reading into things too much or if this actually happened. I have no proof, just instinct and suspicions, and I have no idea what to do about it. Because I have no proof to leverage myself, confronting my wife would likely just lead to massive fight in which I come out looking like the bad guy.
Has anyone else been in a situation like this? Could you offer advice? Also, sorry for divulging my entire life story. It's probably a horribly boring read.
