A few years ago I had a very similar experience.

I met a guy in college. We dated. When I moved in things seemed to change. He became more comfortable with being 'too honest'. He started to act like there would be no repercussions for the things he would say because I moved into his place and I was 'stuck' with him.

His house was given to him by his dad. His sisters lived with him which he also didn't tell me about. He only wanted to work 4 hours a week and had no motivation or ambition to do anything. When I did try to mention it to him he'd reply sarcastically "oh I'm sorry my dad died and left me this house". His father passed away 3 years prior but would use the excuse anytime him getting a job would come up. His sisters lived there and supplied him with food and extra money.

Basically, I was sick of the nonsense. He stated he didn't like majority of his family but would use the excuse of family for not working or for acting a certain way. I was tired of the apologies and being belittled about my ideas for the life I see myself having. Any hobbies of mine were 'dumb' or 'not worth it'. He'd then say things like "I wouldn't waste my time but that's your choice". Basically a complete turnaround from the supportive guy he was before I moved in.

This whole thing lasted less than a week. I moved out and would rather live with family than live with someone who puts me down, or doesn't want me to succeed because they lack the ambition.

After endless calls and emails of him trying to get me to move back. I told him it was better we don't live together. His truth of what he thought of me came out. He called me every name in the book he could think of. He stated I was "like his bitch mom and every other woman who walked out on him".

If you're gut is telling you something, its best to listen to it. I'm sure he wouldn't like it if you started insulting his favorite TV show, or game or whatever.
