I also wanted to add that until I had a child myself, I never truly understood what my mother was going through with my sister. I just knew that I had become very protective of my mother and it would hurt me to see how she wasn't getting the love and respect that she worked so hard for and totally deserved. I remember those two wouldn't speak for a few months and then my mom would allow contact again and I'd say, "Mom, you're just asking for her to hurt and abuse you again". SO many times I said that to her over the years and she would say, "But that's my child" and I so totally get it now. I feel her pain and yours.
I just had that on my mind last night after I responded and felt it on my heart to tell you this morning. My mom was the best and I'm sure that your son thinks you are too. Keeping you in my prayers in the situation with your daughter ANewLife4Me and wishing you a good day!
