I am trying to get it in my head that no matter what I did that it wouldn’t of worked.  It is very hard though when I changed into someone else during our relationship.  However, I do think if i would of stood up to her, she may have still felt guilty and such.  Making it to a point where she would want to end things.

Like I said, i will never really know for sure.  It’s just hard to let those thoughts go.  Hard to move on and enjoy life now.  Fridays are the worst.  That’s when i got most excited, cause I was going to see her.  I’m trying to be that way now with my girlfriend cause we only get fridays and saturdays together.

Yeah, I really don’t think you standing up to her would’ve made any difference. Think about it this way… the way you were acting was a reaction to her seemingly backing off, right?  That means she made her decision to change things and back off BEFORE you started acting differently. She was already in the process of making up her mind without talking to you about it, so your opinion or thoughts wouldn’t have changed anything, and, who knows, it might’ve made things even worse.  You may be finding it hard to let it go, but all it really takes is making the decision to let it go, and then it’s easier after that. You might want to ask yourself WHY you don’t want to let it go. Is it possible you are afraid you’ll get over her if you let all of this go and then she’ll come back after you do and you won’t want her anymore?

You also seem to compare your current relationship with your girlfriend with your relationship with your ex a lot, which is not helping because they are two completely different types of relationships (long-distance weekend relationship vs. every day real life), and two completely different people, so it’s comparing apples with oranges, you know?  I think it’d help if you’d get yourself into a situation you ARE happy with, even if you just make improvements to your life outside of your current relationship if you don’t want to leave that right now.  You’ll have an easier time changing your mindset if you focus on YOU rather than your girlfriend or your ex although you still do need to think about your girlfriend too, because you’re with her, but I hope you know what I mean… just find some things you truly enjoy and that improve your life.
