My mother and I did not speak for 10 years. She is an alcoholic, I just had to part ways for a period of time. We did not communicate at all. When it was her birthday I wished her one in my heart. That was the best I could do.
We are back together again, yes, she still drinks however she does understand my bounderies, and, she does know I will enforce them.
You should do whats best for you.
