Mixed bag of emotions

I am now in full no contact with my ex, last time I spoke with him was
Right around the car accident back in febr; since my D was with him
In the car and her phone was destroy in the crash I had no choice but
To get in touch with him. My D has been acting very cold and mean
Towards me, when I went to visit her after the accident she scream at
me an told me flatly: "I have no time to deal with you, you need to go"
I left at my witts end and a mess. After that back in April I did a trip
Back home to take care of my grandma, who at 94 is still the strongest
person I know, after receiving the phone call that grandma was in a emergency
surgery-hip replacement as it turn out-I call my D to let her know what
was going on and she answered: " And what am I supposed to do?"
I was livid and stop talking to her, a week later she texted me:"oh so
you are not going to tell me how is my grandma?". I ignored the text.
Then out of the blue she send me a text that she was excited about
a date she we going to, I went to see her shortly after and we talk so
e girl talk and towards the end I did told her she hurt me when she did
the comment about my grandma and that she should at least call her
and talk to her for 5 min-that did it for her she kick me out of the
apt again-that was back in April. I have not seen her yet. She did not talk
to me for mothers day and yesterday texted me about some problem
with the train. I feel she has taken me for granted and frankly I am
getting tired of her childish behavior. But whenever I try to bring this issues
she will kick me out...lately she refuse to call me mom and I beginning
to wonder....should I call her daughter?
