Sounds like everybody oughta be ashamed of Grandma instead! What business is it of hers or anybody else's about OP's choices in her social life? Being single isn't always a voluntary decision at times.... :-(

Just for curiosity’s sake... how old are you?

How fat is she that half the family is required to lift her up?

IME if female relatives try to shame you into a relationship/marriage, it's because their own sucked and misery always wants company. Usually they can't deal with the prospect of another women just enjoying her freedom because that means she's not tied down to the hyena table of unhappily married women who actually despise their situation yet insist that everyone join them or be shunned as selfish and unloveable lmao. Internalized misogyny is a real b*tch. The time of financial and social dependency on a marriage for women is long gone, some people just have a hard time grasping that concept. I'd argue getting wasted at a family reunion before insulting people and passing out is more of a reason to be ashamed, but you know, different values here.

Sounds like it’s time for you to choose your own family.
