Is it just me??

My girlfriend and I have been living together for about a year. She has a lot of male friends which I am totally ok with. But she also stays around their houses when there doesnt seem to be any real need to. They are all single male friends, and I have a real problem with it. Whatever I say about it she just thinks I am wierd and too possesive. Would you be ok with this or am I going off on one about nothing. Could use some opinions as this is doing my head in!!! Tweet
