Keeping hitting a brick wall

Seems like i can never find the perfect guy for me. One day he's calling me baby the next he's making it crystal clear he doesn't want commitment and says it's only a matter of time till he's gonna bring over a new girl. How can it turn from being a perfect life, the suns shining and i'm just on top of the world, to being discarded and this is just a temporary point in my life. Can't go anywhere else cuz god knows, nobody can find out about my webcam, and after getting an awesome check just showing off some skin and chatting in my chat room, i can't go back to handing menus and wearing some tacky uniform or flip burgers and go back to struggling. So basically i'm trapped in a place where i can't exactly go find mr.wonderful while still living with him, but i'm suppose to wait till he tells me to move to the other bedroom. It's perfectly okay for him to replace me, but it'd just be awkward and wrong for me to start seeing someone.
What is so wrong with me that duche bag after duche bag, come flocking at me. WHAT AM I DOING WRONG????? I knew how he was but i thought....i don't know what i thought. It doesn't even matter anymore. He hardly talks to me, he's always finding stuff to do away from me, having phone conversations away from me....he's planning something and i'm not in the loop.
I guess i'm stuck just doing my cam, and save up money in case shit goes down and gets too bad. I'm not staying in the next room over listening to them having sex.... This is just a shitty situation. I have feelings for him so it's still hard for me to in his face find someone else... I guess i'll save up for my own apartment instead of a car....Wasn't picturing this situation when i was riding a bus thousands of miles away from my friends and family. The webcam job is the only thing that's good in my life right now
