Just try to think about everything that has bothered you about that person. Every little flaw, even the stupid ones. Then you just try to think about happy things, and do things to keep yourself occupied so that you are not thinking about this person constantly. Refresh your mind. If you can, think about someone else, someone new, who will commit. Hope this helps! :)
He is not into you or he's to young to want a relationship,if he loved you he would BE with you. Guys are black and white like that.We are the complicated ones. Honey don't waste the pretty. Find a guy that thinks you are the stars and the sun and treats you no less than the queen you deserve to be treated like. No compromise.
It's that's he won't commit, is why your obsessing. Admit that and then I think you'll be able to get over it. Because you think your obsessing because there's that "there's something about him" feeling. Yeah it's not real, because the only thing about him is, that he doesn't want to commit that's it. People want what they can't have, your stuck because you don't understand why not commit to you. But that's honestly his problem his choice.
Well as a guy I can say if he doesn't want to commit then you have to accept this and just be friends (if you can) with him. If your feelings are so strong that you can't be friends then you need to move on because it will bother you and eventually affect your relationship and views of him
Find someone who shares in the same qualities as you or in what you want in or for a relationship its best too ask the next guy what he thinks about commitment and stuff when you have talked for a decent while like three or five months then ask him but not right away thow and don't waste anytime asking or telling the person what you want in the relationship maybe its best to tell the person what you want so your not wasting your time
