Am I obsessed with my girlfriend?

You're just overly infatuated with her. But you're possibly a bit too clingy. Girls may get scared off by that sort of thing, and perhaps you need to stop being so jealous of other people, because she will notice it lol. I think if she does wear revealing clothes, it is her prerogative. You can't make her be something to please you. Also most men adore their women in revealing clothes, because they have something beautiful to admire and feel proud of being with. You seem really nice and a loving boyfriend, but eventually your jealousy will come out; and you could end up being controlling without meaning too...and she may end up resenting you for it. I think you need to treat her well, keep as your going and completely brush these hugs (and things) under the rug, because it's not important. It's unhealthy to be friends with only one girl or only one boy. It's unhealthy to always be together...the relationship will get crowded. If she was doing anything bad, she'd be trying to do a better job at hiding it than just telling you. If you want this to work, keep as you are, minus the jealousy...she will realize and it will become annoying. Don't dedicate yourself too quick, have fun for now rather than getting serious!
