Thanks everyone for the advice.  I think now in addition to moving out and living with my friend - who is just a friend, yes he's a guy, but he's not my type of guy as I like guys that like girls 

.  So we would definitely be living together as friends.  But now I do sort of wonder if I should live with him, not necessarily b/c I think I should be living alone, but because I'm starting to think that he is looking to find a place for him and I'm just there to help with rent, even though we are friends and would hang out and go out. But living alone would add a lot of expenses onto what I already would be paying with a roommate (more rent, furniture, etc).  
I get what everyone is saying about I could still live at home and be social but its hard for someone who isn't social to just go out and join a club, volunteer, etc. by yourself.  Chances are everyone there is going with a friend and I've never been the just go by yourself kind of girl.  Living with someone my age I think will make going out and doing things and meeting people a little easier.  Maybe its just me though.  I just don't want to be almost 28 (when I graduate) and never having lived away from my mom.   
I'm going to my DB, DSIL, and niece and nephews today to re-celebrate my birthday so I might mention it to them.  Maybe if I could get my mom not around they will give me a different answer than if she was there.  We'll see.  Thanks again for the replies and I will keep everyone updated.
