Can my boyfriend kick me out and put my stuff on the street?

Question Details:

I have lived with my boyfriend for about 3 months. He has made the comment that if he ever kicked me out I would come home to find the locks changed and my stuff out on the street. Is he able to do that or do I have any legal "residents" rights in IL? The house and all of the bills are in his name. I do get my mail there and contribute money towards the bills and expenses.
