<human>: I'm going to post here under the assumption that a lot of people have dealt with a similar situation to what I am experiencing now (this may or may not be the case, so let me know). For some background I have been in a LDR for 6 months now, and while it's been extremely difficult, I believe that my relationship now is very strong and that both my girlfriend and I love each other very, very much. That being said, let me explain a few things: After 5 months apart my girlfriend cheated on me with a friend. In retrospect I'm not entirely surprised that it happened, and I've forgiven her and we've moved on. Don't get me wrong, I know she will do probably cheat on me again at some point, and I can't say that I particularly care so long as she still loves me (sex is just sex). We've come up with rules for our relationship to help with this eventuality, so this isn't where my issues come from. The problem here is that the act of her cheating on me has caused me to become sensitive to my own insecurities. Right now I don't feel particularly attractive (although I am, physically) to my girlfriend or to women in general. I have a very strong desire at the moment to try to have sex with other women for self-validation, even though that's not supposed to be where self-confidence comes from (I shouldn't have to depend on the opinion of other people in order to feel good about myself).

1) Should I mention how I feel to my girlfriend? (I don't think that the discussion would ruin our relationship, but she would feel extremely guilty at causing me to become insecure, or at least that's how she'd see it) 
2) Has anyone else had similar feelings in the past and managed to deal with them in a more positive manner than just banging everyone you can?

Can you provide a brief overview of the text?
<bot>: I no longer feel that I'm attractive, and feel a strong urge to sleep with other women besides my girlfriend in order to validate myself. How can I feel better about myself without resorting to unhealthy behavior?
