he loves me a lot and forgave me but my love changed after I did this. We're not together now but we are still friends.
I think MessedGirl meant this about her (ex-)boyfriend, right? If so, I guess you did the right thing, to break up, even if only temporarily, so that you both get time apart from eachother to evaluate your feelings and sort out what you want for yourselves at the moment.
As for the other guy, the only way to know what he was thinking and what he's thinking now, is to have a good conversation with him. Call him, use the internet, email, whatever, tell him exactly what you told us, what you feel about what you both did, what you feel about him, and that you'd like to know what he feels too. Point out that you're not trying to start a relationship as you think it would be hard being that far away (so he doesn't feel pressured), and that you just want to know those things so you can sort out what's going inside your head now.
Hope that helped, and good luck Oh, and keep us posted if you want
