I know I cannot make adults like each other, but how can I get family together to at least be together?

Well your mom might have her reasons for staying away, some wounds are harder to heal then others, and some people (even family) won't change. There might even be some embarrasment or envy. If you want to carry a relationship with your extended family see if your uncles are on facebook or even their wives, cousins, etc. Before you do anything you really should talk to your mom and tell her your feelings and ask permission to carry on. But do not play negotiator. This is really up to them to fix it, if they want to. You can just ask for a ride to visit for a birthday party and an occasional sleep over. I am sure after a few times she might be willing to take baby steps... Good luck
