<human>: Can you provide a brief overview of the text?

I'm going to try to keep this short and sweet (if possible). BF and I are both college students and we've been dating officially for 7 months or so, hooking up on and off for about a year before that. Up until a month or so ago, our relationship was fantastic. He's my best friend, we never fight, we have an active sex life, he treats me so well. He's absolutely crazy about me, and I love him too. My only gripe was that he's a bit irresponsible (in terms of keeping his room clean, doing homework on time, etc. Nothing major, just typical college guy stuff). 

For the past month or so though, I've been having thoughts and fantasies that make me feel incredibly guilty. I am not lying when I say that I love my boyfriend, but part of me really misses being single (I've been single since college started up until we started dating, and I've just been doing the NSA hookup thing). I miss the thrill of hooking up with someone new. I already mentioned that my boyfriend and I have a very active sex life, but I can't stop these thoughts. The fact that I've gotten asked out by a couple guys in my classes this term hasn't helped. Please note that I haven't done *anything* that would even remotely be considered cheating, emotional, physical or otherwise, and I wouldn't ever. It's just the thoughts.

In an ideal world they'd just go away and I'd be fully satisfied with my monogamous relationship, but I don't know if that's going to happen. I've been waiting it out for weeks and I still find myself thinking about how awesome it would be to be able to live the single hoe life again (lol... but actually). I would never even dream of cheating, but the thought of breaking up and losing my boyfriend also hurts. I guess in an ideal world we'd have a non-monogamous relationship, but I know he'd never go for that and I'd never suggest it; it would crush him. As I'm sure him knowing about these thoughts would. :(

I guess any advice, insight, etc. would be appreciated.
<bot>: I've been sleeping around since college started, now I'm in a monogamous relationship. I am 100000% loyal but am having unwanted thoughts of how awesome it would be to be single again. Help.
