What happens to people that don't relate to their relatives?

I’ve always thought about what happens to people that don’t get along with their family. I’m not talking about teenage hormones “I hate you!” I’m talking about different people that have nothing in common, don’t respect one another, etc.

What happens? Do they move away from each other and not keep in touch?

My family is extremely dysfunctional, and saying that I can’t stand my mother is an understatement. Shes always made me the adult in our relationship which leaves a bad taste in my mouth.

When you have legitimate reason to not want to see these people anymore, what would you do? Or what have you done, for experienced flutherites.
