That’s a hard situation, but breaking it down into incremental pieces might make it simpler. In order to answer your question completely, I’d have to do quite a bit more personal development and many probing questions.

Specific and beneficial internet advice about relationships and friendships is rare for a reason. I wouldn’t ask anyone here anything more than their broad social philosophy, and even that might be poisonous. Hit up the most socially cognizant person you know, as they will have infinitely more context than I do.
