Grandma is it normal...

My mother had always been verbally and physically abusive, obviously the physical abuse has stopped because I’m super grown but she is still mentally abusive She got super pissed at me because I had my entire house painted and stated that I was trying to kill her grandson due to the fumes even tho she has 2 grandchildren myself and my husband child he’s 2 she barley speaks about, anyways we stayed in a hotel to let the paint dry I haven’t heard from her since that was a month ago and now she’s ignoring my kids no call or nothing my oldest son has a phone and there has been 0 contact how do I learn to cut her toxic behavior I feel like this has been going on far to long mind you I’m 11 weeks pregnant and she doesn’t want me to keep it either...smh
