broke her trust

[Classymusicsnob]

I've been in a relationship with this girl for a few months and we hit off very well. I've never ever connected with someone so well, and neither has she. I have NEVER and will never cheat on someone, but I somehow managed to break her trust. I broke trust with someone I actually care about. While we have only been dating for 4 months, and we only have about 2.5 months left before we go separate ways for a while. I feel like I messed up any future possibilities. I got a text from another girl that my girlfriend didn't like. My GF never ever met her, but I guess is jealous of her, even though we never did much before we started going out. So I replied to the girl via text and I said we should hang out. I really don't know why I said lets hang out instead of telling her that I don't want to. Because in reality I would never go through with hanging out with this girl, because my gf despises her. I really don't know what was going through my head. Then the girl posted she was coming to my home town on facebook apparently. My girlfriend saw the post and didn't say anything. I didn't even know there was a facebook post! Then yesterday she threatens to break up with me and I convince her not to, and then she claims she doesn't trust me. When I texted the girl, I just expected everyone to go on with their lives and id eventually get a text saying "when are ya comin to visit?" and I would say "I can't." I never expected this to happen. Now all trust is lost, I am being compared to my GF's scumbag exes, I can't be trusted anymore.... Before you write something down, please don't ask why I texted this girl and said we should hang out, because I don't even know why I did myself. How do I regain her trust? I would love to be a part of her life after I come back from my Europe trip. We planned on that before all this happened, but now... Well she can't trust me anymore, just because I had a dumbass moment.... Yes I know the paragraph(s) are broken and sentence structure could be better, but I just want some tips/info/help on how to win her trust back.
