Welcome Punk...... well, haven't been estranged but nearly there many a time. I have a daughter and 2 sons, all of us live in the same town. Daughter and older son are such difficult individuals. I hardly hear from my daughter because she is busy. I understand, she is divorced, 2 teenage children and all that ....but surely she can find some time to visit me. I always make an effort to go over to her house or I would never see her...we always butt heads and sometimes it's better to keep away. We had a row once, and she did what your daughter did and almost cut me off. I went with a tail between my legs and everything was fine, until the next row.
Two years is a long time, if your daughter lives in the same town. ..was there a big fallout. To cut your mother out of your life for no reason, seems so cruel and drastic.
And btw, if you feel like posting on FB, don't let her stop you. She is ashamed of her behaviour, that's why .
