Yes. He is. He had quit the lifestyle but went back to it because they “understand” him. What they understand is how to be a victim. We had a tough childhood. He still hasn’t dealt with it.
When I had enough of it, I let them know - sometimes verbally, sometimes not - that if they wanted me around, they should try acting like *persons* rather than stereotypical queens. If they persisted, I walked away. Sometimes, it worked. I let them know that I had boundaries, even though they didn't.
Your brother has no spine, and that's part of the problem.
