In love with 2 ex gfs?

Ok basically...I went out with my ex girlfriend for 2 years, we generally got on very well and we had some amazing times together but in the end I split up with her because she was a complete control freak and I felt trapped, like I was married to her or something.

A month later (last summer) I met this amazing girl who's 2 years younger than me, she's very similar to my ex in both looks and personality but without the control freak aspect, and I felt incredibly close to her after a few days of going out, like she genuinely understood me. She was even fine with my ex coming round in floods of tears practically every day. Anyway, our relationship was amazing for a month until I went away to uni in September, whereby we started having a LDR. At the time she didn't know what she wanted to do for uni, where she wanted to go etc so we both found it incredibly hard to sustain our relationship. To make matters worse my ex gf goes to the same uni as me, and was constantly putting my current gf down and finding flaws in everything, saying how much better off I'd be with her etc. She then gave me an ultimatum saying I had a week to decide who I really wanted, her or my current gf.

Being the idiot I am I broke up with my girlfriend, regretted it straight afterwards and got back with her a few days later. This has been going on and off since September until now because I can't seem to make up my mind on what or who I wanted. My parents and friends preferred my original ex-gf as they all knew her well and she came from a nice background etc, whereas my newer ex-gf seems to have bad luck in everything and has a pretty unstable family life. The thing is I've started to believe this over the past few months, I started seeing all sorts of flaws on my newer ex-gf and over Xmas, me and my original ex-gf got on really well and I've recently started having loads of fun with her again. Therefore I decided to stop messing around, put my feelings aside for my newer ex and get back with my original ex-gf.

I told my newer ex-gf about this and she was absolutely crushed, as she had just got an offer from the uni I attend and we were previously looking forward to a fantastic future together (when I thought I'd made my mind up that I wanted to be with her). She's really taken it very badly, but she says I can't go back on my decision now I've made my mind up, but now I can't get her out of my head. I really did/do love her; I just wish I'd met her at another time. I'm worried I've made the wrong decision but I can't exactly change my mind now can I?

So my point of this post was...does anyone have any advice of any kind as to where I go from here? I've really messed up :s-smilie:

Thanks for taking the time to read this post if you have, I really appreciate it (sorry if it's a bit jumbled, I don't want to use the names of ex-gf for obvious reasons). Any help would be gratefully received.
