I'm pleased to say (and I hope I don't sound smug) that though I have a far from perfect family (who has?), I'm not estranged from any of them for very long.
You really have to talk, and for your sanity, try to forgive.
Forgiveness is the intentional and voluntary process by which a victim undergoes a change in feelings and attitude regarding an offense, lets go of negative emotions such as vengefulness, with an increased ability to wish the offender well.
Tough, but extremely rewarding!
