UPDATE:
I posted the below in January. It's now September.

I've since (since that original post) kept my distance from my parents - and gone very low contact. I've been in heavy therapy - and life has felt lighter in recent months.
My Uncle (Dad's brother) went to visit my Mum on Wednesday - to give her a lot excess fruit and veg from his allotment. She apparently immediately started crying to him and said she hasn't seen me in so long.
Two things can be true at the same time. She can be genuinely sad/lonely (especially since my father is away for two weeks) - but it can also be a manipulative tactic given since she knows I talk to my Uncle a lot. I believe it's the latter over the former.
AIBU to think this is just a ploy? I didn't react or say anything when my Uncle contacted me to tell me about her tears etc...
