Don't move in with him. It will only get worse.
I had a homeless work friend that I let stay whilst she found a new place to rent. Why was she homeless? Her housemates were all horrible to her then kicked her out. I witnessed how horrible they were to her so I didn't doubt her version. They'd ganged up on her and bullied her. It seemed believable.
I realised in less than a week of sharing my home why they'd asked her to move out. I learnt from mutual friends how she'd tried to control her ex housemates and quickly experienced myself how her way was the only right way to do things.
If I used garlic the whole house stunk and the windows had to be open and air freshener sprayed extensively. I was told to use mouthwash. Did I have to use garlic? Did I not smell how disgusting my breath was and how much I stunk. Did I not want a boyfriend?
She liked washing up done straight after a meal. Why wasn't I doing the pots? Why haven't you done the pots yet? You still haven't done the pots!
There were lots of other things. She always wanted to change things to suit her. We had words and I had to tell her it was my house and I would be doing things my way. She needed to find her own place. Thankfully it wasn't long before she moved into her own flat and we resumed our previous work friendship.
She made lots of comments about me not being attractive to men because of my slovenly ways, unfashionable clothes, stinky food choices, lack of makeup and hair styling and hippy ways. Strangely enough it is her that has never managed to progress further with any of the people she dates. She has never lived with anyone else.
