I need serious dating advice. Help?

Ohmygosh. I would freak out too if some chick posted something like that on my boyfriends wall!!! Well, confront him about it. He shouldn't have a problem with it, he should understand that it bothers you alot. If you ever see her, slap that *****! Haha I'm kidding, don't. But yeah, ask him!! Good Luck :)
