help me

3 weeks ago, my boyfriend through 1 year, moved to Spain for 4 months (i live in Sweden).
When I met him I had my doubts it this was going to last (he is 20 i am 25, and he wants to travel and see the world, I am busy with college). Yet we were very much in love.
He waited for a long time with his dream of travelling because he wanted to be with me and even suggested we could move in together. However, it made him lazy and unmotivated and he realized he didn't want us to stand in the way of doing what he wanted.
I let him know that I wasn't interested in a long distance relationship from the start (just got out of two unsuccessful ones) but let him go and tried to accept it (after serveral days of crying about it to him).
It went fine...the first week. Then i exploded in some sort of hysteric fit. I would loose my temper over stuff like him saying there was beautiful girls in spain. or that he didnt have time to talk to me everyday because he wanted to enjoy his time there.
I thought he was being selfish and should respect my needs since he took control over our relationship by turning it into something i didnt want...a long distance relationship.
i thought that he wanted to be single and didnt need me. and that he was having a good time without me made me doubt that we were right for each other after all.

He did choose to be away from me and is fine with it. I dont know what to think anymore, I tried not contacting him (which makes me ace even more). I tried to talk about it (which makes us argue for hours), i tried to be positive only (which was fine but with me temper, didnt last very long)
Yesterday I was deciding to break up with him after my fathers advice, but speaking to my sister made me wanna try and just be as cool about it as possible and try to convince myself that he actually didnt leave me, that he does love me and that he needs me.
Am I crazy and need help or just being unreasonable?
Or is this just a kid who is only thinking about himself.
Please help, everyday is an agony.
