I'm so confused?

Went out last night with ex girlfriend, we started talking at dinner and she was telling me how she feels and felt about certain things. Was mad that I never took her golfing when I said that I would teach her but we broke up before May and so I never had the chance to take her out to do that... I went on my golf league trip like 3 weeks ago and she said I didn't even tell her I was going and that she would've loved to have gotten 17 fireballs deep with me (she actually had covid when I went) She would then say how I would never include in anything... but how am I supposed to when we're not dating? And barely talking... we went 2 months without seeing each other... and I liked one of her friends fb post like 2 weeks ago that said "if you see me out with someone, mind your business I'm doing interviews"... she was like, I guess that shows me where I stand and all... I'm just like all confused by this... we haven't been together since April... my head is just spinning... we stopped talking about it at dinner and I didn't wanna bring it up again right before bed cuz I knew she was tired and had to work early today... I stay over her place everytime I'm there... any advice on this would be great. Why would she say all this?
