Should I avoid this guy who seems to have different girlfriends every week?

Hm. This is a tricky question. I think it would depend on what the guy is like. Does he come across as a normal, down-to-earth guy? Or does he strike you as a "player?"
It's not my place to tell you how to feel or what to do, for that matter, considering I don't know him. However, I would advise that if you are to pursue him, take caution. Chances are he likes to move from girl to girl without having any feelings for them, like a new flavor each week. Don't let yourself fall too hard for him if he is like this, because you will only hurt yourself in the end.
Hope this helped
