I'm not sure what you mean by not being a match for anything besides the bl orientation. You are a bl and you can't change that, so why would anything else even be in question here? That's what you are and can expect to be, for ever.

As for the boy, it seems you've made some truly grave errors. Why would he think of you as a toy unless you've let him use you like one? Why would he think of you as a bank account unless you've acted like one? I guess maybe it's no help to point it out, but it seems you are reaping what you sowed.

We aren't called to be a bff. Boys don't come to you looking for another friend; they would go to someone their age for that. We are to be role models and that involves saying no as much as saying yes. That involves being firm and strict as well as loving and kind. You can't just get them whatever they want and do whatever they want, you are the man in the relationship and it's a man they are after (or else you wouldn't be in a position to be their AF). So, man up.
