<human>: Okay so, i've been seeing my girlfriend for almost 2 years by now. I have been really happy with her, and i do love her. But lately i've just been thinking a lot about whether or not this relationship is the right thing for me.

Well, last night i went out with 3 guys from school, i was drunk and in a good mood, and the club was packed. Me and one of the boys start talking to these 2 girls, just superficial joking etc. but after i while i started being somewhat interested in one of them. 

So i end up talking to this girl for a couple hours outside, after the others went home. In the end i got up and said bye, we didn't exchange numbers or anything and i have no interest in talking to her again really, it was just cool to experience it all again, talking/getting to know girls (with other motives than talking) - not that i would EVER act on anything while in a relationship.

but it did make me realize that i'm almost 22 and there's not too many years left where going out every night meeting new people, and new girls, is as possible as it is now. I've had this thought for a while but this just confirmed the feeling.

Another thing holding me back is that i really do love her, and i'm her first boyfriend/first nearly everything, while i've had another long term and a ton of flings and short terms. So i recognize a lot of her behaviour from my own first long term, and i did not handle that break up well at all. Now i'm really scared of her experiencing the same as me. She is a wonderful person and she really does only deserve to be happy.

I'm pretty much sure i will regret it no matter what i do, because i don't really want to be with her but i also don't really want to not be with her.

Can you condense the text into a few key points?
<bot>: 2 year relationship, realize i have spent most of my youth in relationships, want to experience the world by myself but at the same time don't want to leave my girlfriend. Wish i had met her later in life.
