text: Bring it up to them, and ask them why exactly are they doing that to you?  If they are not understanding what you are talking about.  Then explain to them what your feelings are, and tell them if they keep doing it, that your going to stop hanging out with them.  If you have already told them your feelings, then stop hanging out with them and let them see that your serious about your feelings.  A true friend is not going to do that kind of stuff anyways.
