"I no longer like you for doing something I asked you to do" - This guy is a grade A dickwad.

Nothing wrong with having a fwb but just try to pick one that treats you with some respect. One who doesn't try to convince you do things for only his benefit.

You're better off without him.

We all have different types so I won't go into specifics of appearance.

Work on self confidence and being happy. Nothing is sexier.
