you may be in the right.
nevertheless i would extremely strongly advise you to drop the matter, swallow your pride, learn to live with it, even smile and be friendly and do not mention it again.
if you do this for the sake of peace between Jews, for the sake of avoiding machlokes, for the sake of Hashem, even though you are being wronged your reward will be inestimable. just as you overlook the wrongs committed to you, so will Hashem overlook the wrongs you have committed to Him. The Reward will be inestimable, great beyond comprehension, real, and forever.
you will have to overcome your pride however, very very difficult. speak to a wise Talmid Chochum if you can find one, preferably with a long, grey beard. learn the Mesillas Yesharim on pride
