My grandma (78F) has lived with me for the past year after some health issues. I (29M) work from home, pay all the bills, and do most of the caregiving. Lately, she’s been getting mean—not confused, just mean. Constant insults, calling my girlfriend “the maid,” hiding my keys, telling people I hit her (I don’t). Last week she let my dog out on purpose. I caught it on the Ring cam. When I asked why, she said, “I wanted to see if he’d come back.”So I packed her stuff and took her to my aunt’s. Now the whole family’s calling me heartless. AITAH for deciding I’m not equipped to care of my grandma?
