Girl 1:
Used to date her a while ago (over a year ago) and we split after about 6 months due to multiple minor reasons but there were no huge major reasons for the split - it just didn't work out at the time.
She's short, blonde, cute, slightly older than me. A nice girl, but not the sort of woman that I would go crazy for. She's just an all around decent girl, cute, and fun to be around.
Girl 2:
Never dated her, we were just fuck buddies.
She's 5 years younger than me (I met her when she was 18) just before she went off to college/uni in another city.
This girl is smoking hot (like almost model hot - works in a Hollister store), bit of a slut, bit of an airhead (but not a total bimbo, she is well educated). Oh she's also kind of crazy/insane. Anyway, she was an amazing fuck, absolutely stunning, but we would only ever hook up to bump bed posts and once the sex was over we would always quickly part ways.
So Girl 1 and I have been meeting up for the past 3 months or so.
At the moment we're 'just friends'. We do kind of girlfriend/boyfriend things together e.g. go out for meals, go for romantic walks, hold hands, cuddle. I stay at hers, we sleep in the same bed, we spoon, tickle each other and flirt. She says she 'likes me' yet is still hesitant about us being a couple. She doesn't date often (she's nearly 27 and has only been in three relationships - me included). She's the type of girl that will only sleep with someone if their in a relationship, and she doesn't get into relationships lightly.
I'm cool being friends, and try to treat her as such, but deep down there are prob some lingering feelings there on my part. I'm not madly in love with her or anything, but if she wanted to give it a go, I'd prob date her.
Girl 2 is now back in town (she left her old uni and now goes to school about 20 mins from where I live). She text me on New Years, we've been flirting, and she wants to meet up.
Both girls want to meet up next weekend.
Girl 1 wants us to go to dinner, maybe a movie, and then I'll prob end up staying at hers. There's no guarantee that I'll get anything but if I do go I'm going to try and kiss her.
Girl 2 wants to just 'meet up'. I asked her what she wants to do, where she wants to go, and she just said 'wherever

'. Pretty sure that translates to 'fuck like rabbits'.
Should I see girl 1 first and then try and hook up with girl 2 another weekend?
Or hook up with girl 2 first (which means blowing off girl 1 - who asked ME out) and then see if maybe girl 1 will still like to meet up another time? (I think girl 1 might be a little upset if I blow her off).
I must also say that I can't hook up with either girl the weekend after because I'm going away for the weekend.
