Blinded By Love

This is kind of going to be a rant, but I need to talk about it. A friend of mine has been dating this guy for a little over two months now and he's a dick to her. She is a really sweet girl and this is her first real relationship, and this guy is taking advantage of that. My friends and I have been trying to nicely tell her that this guy isn't worth it, but she blinded by love. So I don't like what he does to her but think about it for yourself. For example my friend and her boyfriend have the same lunch along with me and some other friends. She will go and sit at his table, but he will sit on the completely opposite side of the table from her, one guy feels so bad about it that he sits and talks to her everyday because she doesn't know anyone else at the table. Another thing that bothers me is that he won't acknowledge her existence in the hallways. He won't hold her hand, hug her goodbye, or even talk to her. If he sees her in the hall, he ignores her. He kissed her sure, once when they first started dating. So tell me am I overreacting about this or does my friend really need to drop her boyfriend?
