Yesterday, after work, I went to the store to take just the flu shot, told the person injecting me to give me an extra bandage, which was branded with the logo of the store, put that bandage on in the bathroom, and went home.
Mom asked me where I went, I told her I took the shots, showed her the bandages, she asked if I had my card, I said I did but she never asked for it, and then I went on with my day.
I’m still waiting to see if the shoe drops and she asks to see my card within the next few days, but if that happens, I’ve taken all of you guys’ advice into account, but so far I’m good.
I did it this way mainly because my appointment time, but Mom wasn’t mad or anything that I went without her, last night was just a bit hectic, but hopefully it’s over for now. I’m still looking for places to move, as I definitely don’t wanna deal with this again, but damn, I didn’t know that lower income housing had waiting lists.
There may be some that might rag on you for using deception than standing up to her but you did well by just maintaining your bodily autonomy and not getting that poison.
You have, as you noted, bought time so yeah get options open and see if you can be less or even not dependant on her at all, that's better to reject her when she holds no cards. Have a low and a high bar of how you want to get away from her, high bar is literally own your own place and low being owning your own camper.
Make it so if she burns that bridge, you're on the other side not stuck on her side forever.
