Lightinthesky, unless he is straightforward with you about why he has changed his demeanor toward you, all anyone can do is guess. I'll take a guess and say it's possible that he woke up and the thought of falling in love scared him, and he really doesn't know how to communicate his feelings to you. Sometimes love is like a trap - you walk in and it springs shut.behind you. From there a person can panic & do any number of things to flee the trap (lol). It's a smothering feeling. I know about that trap. I had an online "friend" ... Neither of us expected our friendship to become as meaningful as it did. Long story cut short - the trap door slammed shut - and I felt trapped in a situation I knew could never be. I had to break out. It was impossible for me to tone things down to be just casual friends - the only way I knew to do it was cold turkey. It hurt - oh how it hurt. But there was no other way. I knew that eventually we'd both get over it, whereas if I didn't cut it off cold like I did, it would have destroyed us both.
