It’s all been a lie

I just found out my bf of 2 years has been nothing but a lie from the start. He said his sons mom cheated on him, he was cheating. That his other gf was cheating, it was him cheating… I found out he never actually took care of his son until he was 4. I found out that he was actually charged with theft, perjury and it was because he actually did it not just someone setting him up. I found out that he use to stalk and slash the tires of his sons mom. I found out that he made them have sex with him after a fight. Like he does me. I’ve tried to give benefit of doubt. He’s starting the pattern that I could write about for a mile long to me as he did to the past one. I’m scared to leave. I have no family and 2 kids to look after. I can’t just up and leave because I have to find a place to go. Nothing is in my price range available right now. I’m disgusted. I’m angry. But once a narcissist always a narcissist? I thought he truly loved me, but does he??? Ugh.
