I undersand what you are going through to a certain extent. My personality and ways are different.I really have never cared what other people thought of me. My father wanted nothing to do with my brother, wasn't even to speak of him so I asked my stepmother to tell me what she knew. To have other people make the decision I wasn't to know him or him me is selfish and controlling. I didn't look for my father's son, I looked for my brother. Whether or not your Mother or relatives choose to meet or see him is their decision and should not affect yours. Put yourself in his shoes, and let him know so he can understand the situation as it is. You both are adults not children to be told who you can be friends with and who you can't. Good Luck and please let us know. We will be thinking about you.
