Yes, she may do one or all of those things. She must feel that things are not right between us. When we talk I mainly listen, which is pretty much normal. She rarely asks how I'm doing but she does ask about the pets. She's in her 80's and has a live in boyfriend who has always been jealous of our relationship. I expect he is egging her own, or maybe not, she's capable of doing all this on her own.
I never thought she would use such spite against me. But I've seen her do it to others, so why not?
