My two best friends have this other friend who isn't quite fond of me. I do not find a liking in him either, but we can still manage to be around one another. However, he don't like to invite me to gatherings where he's including my two besties and sometimes it kinda hurts to be excluded and not being able to be around... I would like to get on his better side and be able to spend time with all four of us! What can I do to get there?
