TL;DR - My husband [M34] of 2 years found out some of my [F31] sexual exploits in college. He has barely talked to me since he found out, and I'm afraid our relationship might be finished over something I did 10 years ago before I even knew him. I'll try and keep this short. We've known each other 5 years, been married for 2 years, and up until last weekend things were perfectly fine. Maybe once in a while we'd bicker about money or something, but 99% of the time we were happy together. While out last weekend for a friends birthday, a (now ex) friend of mine told my husband about a relationship I had in college. My husband knew about my college boyfriend, but obviously I didn't share intimate details about our sex life. Well... it came out that I used to engage in threesomes with him and his male roommate. Probably 12-15 in total, but all my husband knows is that it was 'more than once'. College was a totally different time in my life. I was drinking every weekend, doing recreational drugs every month, partying, having casual flings - just like everyone else at that age. It was a hedonistic "live for today" lifestyle that I thankfully grew out of. I look back on those years with a lot of regrets, and not just about my sex life. I mean, it was 10+ years ago. I'm a totally different person now. Regardless, I know my husband sees me in a totally different light. He hasn't slept in our bed since he found out, and he's barely spoken to me all week. I'm so scared he'll divorce me, I'm walking on eggshells just trying to stay out of his way while he works through this. I really want to sit him down and clear the air, I just don't know where to begin... I feel like one slip of the tongue and our relationship could be completely over. I know I'm not a good person for keeping this from him, so please don't lecture me. It was a chapter of my life I'd thought I'd closed for good. It was my ONE secret, and I honestly debated telling him about it but came to the conclusion that no positive outcome could come from it.
