my grilfriend of 4yrs has suddenly stopped talking about sex , long distance relationship
I don't no if I like this guy or not. He treats me very good but I am just not sure what to do?

OK, I'm confused here. The original post is from a guy right? And then Hockey Chick wrote she doesn't know if she likes this guy or not? Can someone clarify?
