Why not confront them? Be open about the way these people treat you. Make a matter-of-fact statement, not a blatant accusation. Ask one of them, or both, if you can have a few private minutes with them. Ask, "Is there something I've done that has offended you? I ask this because I don't feel well accepted when I'm around you. Will you please explain this to me?"
If they remark that it's all in your head, them repeat to them what they've said to you or explain to them what it is you're encountering while around them. It's oftentimes better to get it out in the open, bring it to the light.
For many, many years, I was seldom acknowledged while I attended several Charismatic churches in my twenties. Very little money was I able to give to any of the groups because I was struggling financially to get through college. To them, it was obvious, I was a pauper, and therefore of little use toward paying the bills, despite the fact that I helped to lead worship as the groups' bass player.
Years later, after I was hired for a decent, well-paying position, I bought a home, had a few bucks in my pocket, and routinely attended a nondenom group that met in an elementary school. Unlike times past, I was able to give, and did regularly, through checks that contained my name. The response from leadership was unlike anything I experienced while I was a part of the other churches. The pastor shook my hand, asked me how my week went, and even requested I teach an adult Sunday school class.
Believe me when I write that money can often speak volumes to the spiritually ambitious. When you give, you instantly become a contributor, someone who they can count on.
One day, you'll be able to contribute, and their arms will be open wide to you. It's part of the hypocrisy that is fairly rampant in so many chuches.
