Sharing my story

I'm wanting to share my story because I need answers or something...

Me and this guy had a very complicated relationship. We were together or talking for 5 months, at first it was talking until he finally told me he wanted it to be more. We talked everyday from good morning to goodnight, while he at work and I'm in class. Everything was perfect, us and just basically everything. Our convo were NEVER boring we kept one another laughing, honestly he was perfect he was everything I always wanted in a guy. And what's funny we both weren't looking for a relationship or anything we kinda just fell for one another by getting to know one another. But by the end of Nov he was acting weird.. He would text me in he morning for a little then stop.. text me in the afternoon then stopped... Late at night and stop... It wasn't our regular convo I finally wanted to open up to him but he wouldn't talk to me.. it's been 3 months now since we talked and I can't get over it.. he won't talk to me or nothing, I've been on dates and talked to other guy's. But I still haven't gotten over it, he made me happy and I haven't been that happy with someone in a very long time..

I am 18 and he was 21, our complicated relationship or whatever it was distance. I would visit him because he lives out by my family and I moved so he was only 3 hours away.

It would help to see what you guys think on why and what happened. FYI I never got an answer or explanation from him he just stopped talking to me.... I have him on FB and IG there was no other girl.
