What i should do about my girlfriend?

well my girl friend and me live in IL i live with her and i moved from indy and it seems like everytime im not around shes talking to one of my friends from indy and there a bunch of perverts and shes an attention i told her i dont like it and she didnt care so about a month later witch is today we got into an argument about it and she says i can talk to who ever i want and when i left i slammed the door and she told me that since i did that shes taking me home so kicking me out again everytime we argue she tells me i can just leave or tells me to leave. o and her exfiance died a little over a year ago and one of my friends looks like him she says but he not the only one she talks to. well i know its alot i just need to occupy my mind 4 a min to clam down so what u think.
