They were very young when I was born, only 16 and 19. I have a younger brother who is gay and they have both pushed him away too, though mom a bit less. They were very controlling, highly critical and verbally abusive. The only thing I regret about the lack of relationship is that they managed to drive a wedge between my brother and I. I would thrilled to see him and build a new, grown up relationship, but they have made that impossible.
And for the record...I didn't see either of my parents for about 10 yrs and then decided to try again in my late 30s and early 40s. It proved fruitless. They were more angry, more belittling and just as abusive as ever. I tried, but then again I have changed and I no longer need that sort of negativity in my life.
