welcome.
I imagine the ones that don't speak to you feel you are bad association regardless of whether or not you are d/f. As soon as a person stops meeting attendance, many JWs will stop talking to them.
A simple test would be to confront one of the ones that don't talk to you. Ask them "why don't you talk to me, I am not d/f?" If you were, they will soon tell you, if you were not they will make up some lame excuse.
