New Girl, Old Girl... Which one?

Hi everyone, here's my problem

I've been with a girl for a while now. She's really sweet and caring and she's in general.. well a great girlfriend. But lately there have been some incidents which happened and i'm starting to notice that there are some big difference between us.

Before this girl, i used be a player. Crazy parties and one night stands were my thing. But i wanted to try a longterm relationship for once and i met this girl. Everything is fine for a while... but she's a good girl and she doesn't really like to go out at all. I like spending time with her but i'm starting to miss those crazy parties and fun.

Recently, i met this other girl at a party and i could tell that she's sending some signals and it was tempting. Now i know that if i were to go and start anything with this new girl, it wouldn't be anything serious, just some fun.

So i guess my question is does my interest in this new girl mean that my relationship with my old girl is starting to fall apart? I mean i really care about my old girl and i don't wanna hurt her, but does the fact that i'm interested in someone else mean that this relationship wasn't right and that i'm just trying to continue something that's gonna fall apart anyways? and if not, what can i do to get my mind off this new girl and liven up my old relationship?

That's one of the funny things about making a commitment to someone. You have to decide things like that for yourself, and make your choice.
