Broly, so nice to hear from you again and that you're enjoying life. I had a feeling you wouldn't look back once that free-loader was gone.
Really that text should be a joke. I can't even work out what's going on in his jumbled brain. He is an alcoholic, his pride is hurt, and he's frantically rationalising everything so it won't be his fault. There is a possibility he felt guilty about bludging on you, and he's busy finding a way to blame you, but who cares what he thinks?
He probably got a shock when you suggested he leave. Could he have lost his power over you? I wonder how long his parents will put up with him?
In a similar situation I found deleting the text was a huge relief. I hope you can do that too, and go non-contact so he can't mess with your head anymore.
You've got a wonderful future ahead - best wishes.
