Planning my birthday & having so much anxiety

My birthday is next month and I’m planning a girls trip, which I’ve wanted to do for so long. I was overthinking it at first & asked my narc if he’d want to go together instead and he kinda blew me off, then when we talked about it he turned it into a rant and projected onto me, etc. But of course ended it with saying “I’m not saying no, I’m just saying idk” Like of course he’s leaving it up in the air so I won’t plan anything else.

Anyways, my friends started hitting me up and wanting to celebrate me, so I decided f*ck it, back to the girls trip plan it is. But I’m having sooo much anxiety thinking about breaking the news to him. I already know he’s going to flip out and probably cut me off and then say he’s going to go find somebody else.

Which I honestly don’t even give af, I’m just anxious about dealing with his response and anger. I hate when he goes into these rages and rants and then makes me feel like complete shit.
