Do I stay or do I go?

[anyhope]

The plan I have changes daily.. I don't have a steady income to just get up and go. I've been with him since I was 18 and never was on my own yet, so it's a bit scary to take that step even though my friends and family would like to see me move on.
He is going through a serious mlc and I read a lot of posts from other people going through the same thing and not moving, just waiting. But honestly I don't think I can do it. He has no issues living with me like a room ate, but it's different for me. He comes home from work, showers and goes to ow. Last night he got home at 3am. He wants to introduce her to our friends. I spoke to one of our friends who just had a baby and he called there yesterday asking her if he can come by to see the baby with ow. (ow is a professional hooker he fell in love with while he decided to cheat on me) while this friend of ours doesn't know this, she told him very clearly not to bring that skank to her house nor anywhere near her baby.
I'm unable to sleep until he gets home. I still have feelings for him. Im hurting while with him...
It also just happened that the landlord at our house decided to either raise our rent quite a bit or give us 2 months notice to vacate. So far we got a sweet deal on the house, now if we stay they want us to sign a one year lease again. I'm not sure I want to sign a year lease with him.. While financially cheaper, I will most likely go crazy. Not to mention that what if the relationship with the hooker gets serious and she wants to move here... Or if he wants to move out... Or anything of that nature.
I asked him what his intentions are, and he said he's not planning on moving in with her, but he said so many things.. Only half of it is true. What if next week he thinks something different? I'm really confused.. Really really confused as to what I should do..
