Im sure he felt the same but never said anything only that I was his friend
It's difficult for straight guys to have female "friends" and not be (if even only in our deep-down hearts) emotionally connected to and even physically desirous of them. It's just the way we're wired. Why were you so sure that he fancied you the same way you fancied him? What were the specific signals? Have you ever seen evidence that he fancied someone besides you? If so, what were the tell-tale signs of this? How did they compare to how he behaves toward you?
has started giving me the cold shoulder on the txt
How exactly does one do this? I'm not a texting person, so perhaps it's common knowledge among those of you who are, but it sounds difficult to me.
might be a case of he doesnt want you, but doesnt want anyone else to either.
I've known guys to do this - it's kind of like building a harem, or a stable, so that at any time they can move on one of them. Doing so, however, disrupts the mechanics that have been so painstakingly set up and followed so, even though he may fancy one in particular, he doesn't move on her for fear of scaring off the others.
he made it clear that we were only friends (only I know it was more),
HOW do you know? Be specific.
We did everything together and he really was so caring so I can't understand why he's acting like this. When he was here, if I talked to another man he would be there giving whoever I talked to very 'evil' looks
All of this could be attributed to the "harem" model I already presented. There were obviously some strong feelings for, or at least attachment to you, but now that you've moved on and he is no longer local he's dismissing you from his "group." That's one possibility, and I'm not convinced it's the true one.
Is he by any chance gay? If you say "no," is it possible that he is but has not yet accepted this about himself? Or that he simply has not yet come out?
Now - about you. Are you a "1-guy-and-1-guy-only" kind of gal? If so - drop him like a rock and stick with Pawel. If not, enjoy your time with Pawel, and others, and, when possible, this guy as well. Don't cancel the trip. Make sure all the guys know that you're not exclusive to them, so there are no secrets.
Most of all, take miranda's advice to "Stay positive and keep in touch with people who have your best interest in their hearts" uppermost in your mind.
