Got a weird scenario here. A daughter (married with children) lives 1000 miles from her mother. Usually the daughter calls once a week. She started a new job and ended up extremely busy. Did not call her mom for three weeks. Her mother was extremely upset and let everyone around her know it yet never called her daughter to check up on her. When the brother called the daughter to let her know that mom was not happy, she called her. She got busy again and time slipped away. Four weeks later was the daughter's birthday. She figured her mother would call her on that day. For the first time in 40 years her mother did not call her. She expected her daughter to call.
The daughter was hurt and extremely upset that she was the one always having to call which cost her money and she was the one that had to travel with her kids to visit which was extremely taxing financially on the family. Her mother is widowed, has no obligations, and has the financial means to do whatever she wants. The daughter thought about calling mom, but brother sent a message that mom was on the warpath about daughter and how she was neglecting her.
If the daughter calls, she will be scolded and never forgiven. Mom hates to forgive and forget. The daughter is tired of being belittled and treated badly every time she calls. She also does not want to call because she wants her mom to actually make the effort. In addition to all this, her mom is telling everyone that it has been over a year since they last spoke. It has been six months.
There might be underlying issues as to why her mother is worse than ever in how she treats people. She has become downright nasty to another daughter and deliberately tries to humiliate her in front of others including co-workers. She is becoming forgetful and meaner as the weeks go by.
The daughter is being pressured by those around her that she needs to call, but the thought of hearing those snide words makes her sick to her stomach. She cannot face hearing how horrible she is as a daughter and all the other things she does wrong. The daughter did call a couple of times, but the line was busy (mom is on the phone a lot) and her brother warned her that mom was on the warpath against everybody.
Now, that a novel has been written

Should the daughter give into her friends and call? Or should she hold off until she knows her mother is in an amicable mood which may never happen?
