<human>: I (18 M) have been dating this girl (18 F) for around 5 months, but about 2 weeks ago we moved to different states and started a long distance relationship. I have never had a girlfriend before, let alone a long distance one, so this was a completely new experience for me.

We had initially decided we would end the relationship before the move. However, she changed her mind and convinced me to give a long distance relationship a shot, so I agreed. She is an amazing person so I figured that I should at least try this for her, even though it goes against my initial instinct.

Since moving, things haven't been going perfectly. I care about her very much, but I have realized over the last couple weeks that a relationship is not what I want in life right now. She feels quite strongly for me, so I wanted to give the LDR a chance for her sake; however, I have been contemplating breaking up. I just haven't really figured out the best way to do this, without hurting her too much.

Anyway, last night I was at a party and got very drunk. I ended up hanging out with a girl that I have some history with in the years prior to meeting my current girlfriend. One thing led to another, and we ended up kissing for about 2 minutes.

I now feel absolutely awful. I truly care about my girlfriend, even though I have not been totally happy in the relationship, and now I have betrayed her trust. I very much regret my drunken decision, but I know I now must live with this. I guess the right thing to do at this point is to end the relationship... I just wish it didn't have to end in this way.

Anyway, I guess I just wanted to get that off my chest. I feel terrible right now about this whole thing.
