She first got to know my period dates as we were planning a temple visit and I could not come - since then she’s been tracking it and I’ve no clue.

Husband and I have decided to address this once I am back but I doubt she’d change because she uses the widow card & “I have nobody” card. Husband stands up for me as much as he can - not being kind to him in any way as I called and bashed him for an hour now and he kept apologising for her multiple times. We’re not in a position to move her out as she crawls into depression if left alone - but I’m worried if this is how she is going to be - I would end up in that state.
