Others have said it, but I feel it needs to be repeated.

Cut negative people out of your life. This person is one of those people. Make yourself busier. A project. Work. Family. Or just unavailability. Don't feel guilty about it.

I had to make a similar type of decision to make years ago. I had a friend, both of us male, who started to grope me. I kid you not he'd meet me in the bar and he'd get a full fist full of my balls. He thought it was hilarious. I hated it. So I got "busy" doing other things, became unavailable.

Funny, only now when I look back I realise it was sexual abuse 🤣.

Anyway, the point is, you will NOT regret cutting this person out of your life. Was the best decision I ever made, it will be yours too.
