Tenancy laws can be so complicated; I want to make sure OP is protected as much as possible.

A woman who repeatedly asks a man she knows to be gay when he's going to get married and have children is not trying to let sleeping dogs lie.

You can care very much about someone without being capable of becoming their primary caregiver in the event of their parents' untimely death.

If this is something you'd truly like to work on, not out of a sense of guilt but because you would enjoy occasionally reciprocating, there are a wealth of resources out there for the enthusiastic amateur (you are far from the only would-be blow-jobber whose spirit is willing but gag reflex is weak). You have more options than "no blow jobs, ever" and "regular whole-hog sessions to completion that result in vomiting."

If you don't like potlucks, the solution to your problem is "don't go to potlucks," not "insist other people don't have them."

I love the art history ones because it's so little work for me. There's so many paintings that when I look at them, the look on the lady's face is like so clear and her body language and her posture or their physical situation is so immediately recognizable. Anyone who's been in a conversation they didn't want to have, or been getting harangued by a little kid they didn't want to pay attention to or been tired and wanted to go to bed is just like, "Yes, of course."

So many people choose silence after the immediate wake of a death out of fear of saying something out of turn or "bringing up bad memories" that bereaved people often feel forgotten.
