OP, YABU, sorry!
Your other thread is a bit light, and tbh in the greater scale of things, what do you care about what your friend says or doesn't say.. Laugh and dismiss, laugh and dismiss. It's really not worth you getting het up about.
MNers are in the main lovely. Sure they are blunt, but if anyone is out and out hostile, they get picked up on it and often reported.
I didn't really read your thread, because tbh it IS a bit meh, and there are other more pressing things to be concerning myself over if I'm honest.
AIBU is not the place for light threads it would seem, Chat would be a better place for it, but the issue is important to you so you posted it here... hey ho...
Stick with it, you'll see how lovely it is here. I'd say namechange, but tbh there is no reason for you to do so really, unless you want to re-invent yourself.
It's ok, we are all sensitive about some things, you are newly PG, you are allowed to be hormonal.
