I’m in my 50s have a wonderful partner of ten years and a fantastic 19 yr old son. I was diagnosed with borderline personality disorder two years ago due to childhood emotional abuse which was from my mother. I’m an only child and lost my lovely dad a year and a half ago after a long illness. Late last night we were in bed asleep and were both woken by my phone receiving a txt. It was my mum. The txt was a link to a dating site for over 50s!! I showed my partner. I txt mother back saying ‘ I’m not happy, we were asleep, why are you sending me this rubbish? ‘ it suddenly dawned on me that maybe it wasn’t aimed at me but that she’d been messing around with her phone been on dating apps and accidentally sent me the link. She’s a nightmare with her phone. Doesn’t even know how to take a photo but can send me links at 11:30 at night. It could have caused my partner a lot of upset, thinking I’ve been chatting to mum about looking elsewhere, which I most certainly haven’t. When my poor dad was ill and had to have carers in at home she got respite for herself and went out with her best friends ex husband to see a show, have a meal. My dad never knew but it would of broken him. I was disgusted with her at the time. She hasn’t even tried to reach out or apologise. I’m an only child and go round twice a week to do cleaning and meds. Thing is, I think she’s making me ill. Yesterday she criticised my son to me saying how disrespectful he is to her. He isn’t. He does the occasional job for her and to help me. She will hover over him, tell him he’s doing it wrong etc. I just don’t know what to do anymore. I don’t know why she would be on dating apps, she barely leaves the house. Feel like she just wants the next victim to do all her jobs. She has always been jealous of me. How do I handle this going forward?
