My boyfriend and I have been together for a little more than 3 years now. We met our freshman year of college, I’m 21 and he’s 22. When we first starting dating things were great, we were happy, had fun all the time and I truly enjoyed his company and having sex with him, sometimes multiple times a day. About 7 months into our relationship my sex drive went way down; at first we thought it was because I got on the Nuvaring but I stopped that after 2 months and the amount of sex we have has only decreased. When I ask myself if I’m happy with him sometimes I think yes but other times, and more and more frequently, I find myself questioning that yes. A few months ago I was actually really unhappy in our relationship; I went away for the weekend and ended up sleeping with someone else. It was the best sex that I’ve had in a while but I felt so much guilt afterwards and promised myself I’d never do it again. I didn’t tell him about it but I after I got back I did talk about breaking up with him and then things just got messy and I felt so bad that I just changed my mind and decided to work on things. When we were talking about things that needed improvement in our relationship I couldn’t even think of ONE tangible, reasonable thing that would make me so unhappy in this relationship. So, currently I’d say I’m happy being with him, but we barely have sex and I’m increasingly wanting to have sex with other people. I don’t know what to do. I feel like I feel this way because I’m so young and I feel like I want to go and just have fun and not be tied down, but then I think breaking up with him to ‘have fun’ is stupid and like I’ll regret that decision later on, even though sometimes I don’t even think I can see myself marrying him like I used to (although I don’t plan on marrying till I’m like, 28 at least). I don’t know what to do and I’m just so close to cheating on him again.. I feel like such a horrible person.
