help please =(

My boyfriend has acted weird for some time now not wanting to spend time with me and not even coming home. We didn't speak or anything. I love him so much but last night we finished. He hurt me so much by not wanting to spend time with me saying he loved me but never proved it. I bought him a present for Valentine's Day and he still hasn't even bothered to look at it. How do I get over a break up? I love him so much and it's hurting me so bad. He's going out with his friends, got his hair cut, going on sunbeds, bought himself some new fragrance so I know he's doing this to attract girls. He's a really good looking 'boy' aswell =( help please I've got no one to talk to =(
