I'm in a LTR for 9months, lately the relationship has been on the decline- more shittests, more attempts to draw me in to pretty arguments, more overall negativity. My frame is being tested relentlessly.

Last nigh she tells me that she's going to have a girls night out this Friday (today)

Her: I'm going out with my friends tomorro

Me: Okay, where to?

Her: I don't know yet, will you go out with your friends?

Me: Probably, I'll make plans tomorrow

So today I get invited to a BBQ. I inform my LTR.

Her: Okay... Won't you feel awkward there since everyone will be there with their partner

Me: No, not really

Her: won't it feel awkward for you to be there without me?

Me: you made other plans yourself, didn't you?

Her: whatever, I guess we'll need to have a talk.

I'm guessing our relationship has entered next teritory? Could someone give me an outsiders perspective, because I'm quite baffled.
