<human>: Can you provide a brief rundown of the text in within 3 sentences?

Yesterday my SO left the U.S. for Colombia, where she is from, after staying visiting here for a couple months. Like I said in the title, we were only dating for about a month but the relationship escalated very quickly. I have tried to be cautious about getting too serious as she was moving away and we had only know each other for a little while but we both became pretty attached.

I feel awful because we talked about trying a long distance relationship even though I expressed my concerns about it I feel like I led her on and. She called me when she arrived in Colombia, and I again expressed my worried about making a long distance relationship work and we ended up breaking up.

I feel like I'm flip flopping and can't decide whether I'm doing whats best for me and for us, or if this is a mistake and this is something I should be pursuing despite the difficulties. She was committed to making the long distance relationship work for a few months with the hope that I would visit Colombia this summer, and she would be back in the U.S. this fall.

I think the difficulty for me is that I would want to continue the relationship if it wasn't for the distance, and I'm trying to decide if that is reason enough to end it with a girl that I really like.

It might be worth mentioning that she is the only girl I have been in a relationship with since high-school and she is basically the first girl I have had sex with (I have had sex one time before). So I'm obviously not that experienced in handling these things and I'm not sure whether I just got too attached too quickly, or if I should listen to the nagging feeling telling me we could have had something special. Now I can't fall asleep because I feel like I messed up.
<bot>: Not sure if I was ready for a long distance relationship with a girl after knowing her for months, but don't know if I was ready to end things either.
