My friend needs help.

Her mom has been off lately. I think she is in her mid 50s and she already started her menapause. She gets mad easily at her and when she tried to communicate with her, she would just gets mad. She doesn't tell her how she feels. 

For example:

My friend invited her mom to this restaurant that her husband and her husband's mom are going to go. Her mom didnt want to go cause she thinks it was like their bonding time or something. My friend told her that it's not serious, it's just a casual dinner. My friend's mom said she still doesnt wan to go. Before I knew this whole situation with her mom,  I wanted to go but I was hesitant about it because I too thought it was a more their bonding time so at first I didnt want to go. My friend insists that I go because she said it is nothing serious and her mom is not going. That morning of, her mom got a little upset that I'm going. 

My friend said that she has been trying to get along with her mom but she gets at mad for not doing the dishes or complains to her that her husband is playing games too much. 

My friend, her husband and her mom lives together.
