Confusing email from Ex G/F..any help?

[confused in PA]

This was an email I got from my ex g/f a few days ago, give it a read and let me know if anyone has any suggestions on where to take it from there. -- "My head is an absolute mess at this point. so i will be as open and honest as i can, but realize this is all really unsure and confusing. i still talk to (other guys name) a lot and, its funny, i feel like you and i have switched positions in some respect, because now i am the one wanting to continue a relationship from a distance and hoping to be with (other guys name) when i get back. but my relationship with (other guys name) and the relationship i had with you are very different, in more ways than is necessray to explain. although my actions may make it seem different, i was really in love with you. and i never had so much fun as we had together and was never so comfortable being with anyone as i was with you. part of me feels like i would be perfectly happy just having what we had forever. but there are aspects that we're right, that didnt fit. i feel that one of the biggest ones is that the communication was obviously lacking. the fact that you thought of breaking up with me and i had no idea (and i still dont know why, but whatever, its egal now). i must say, it hurts me a bit to know that you couldnt open up to me. and i dont understand it really, i dont understand what i did wrong or what wasnt right with us that you couldnt open up to me. and that was what in the end, really pushed me towards leaving and pulled us a part. i think you can understand that. there are other things too i suppose, but like i said, its a bit unneccessary to go into. and so then when you told me about another girl my heart just sunk. and i realized how i must have made you feel, because the thought of you being with someone else is tough. and i really dont think i could ever hang out with the two of you together, if anything was to happen. its terrible, but it was just always in the back of my head, that if things didnt work out with (other guys name) and i, that i could always be happy just going back to you. im sorry, i know that sounds terrible. but really i am so so sorry from the bottom of my heart that i hurt you and left you like i did. it wasnt fair to you or us. but things are how they are now i suppose. and i doubt they will ever go back to what they were. and i cant say that i regret it in the end to be honest. i mean, i regret how it happened i guess but not that we're apart now. i can say that i had the best time of my life with you and i can say that so many good things came out of our relationship - and im really happy that your life is on track now. so i can be happy with what we had and happy that we can still be friends. because you are one of my best friends. . . yea i dont know what else to say. except thanks for being honest with me now, and thanks for still being my friend after i was a bitch. i should wear a warning to all guys, because i see patterns in my behavior. im always curious and always on the lookout for something new, and im always afraid of being tied down, and i always just pick up and leave at the drop of a hat. so goes life.
