AITAH for being ups*t that my partner cared more about watching her friend leave than our romantic dinner?

So l'm going to start off that this is a dummy account but unfortunately she reads these way too much so I fully expect her to find out so l'm going to change a lot of information.

So me (37m) and my partner (28f) have been together for over 4 years. We've had our fair share of fights over the years and we've sort of broken up several times but we've always managed to get past them. One of her biggest issue with me is the fact that I haven't given her many romantic nights and she wants more.

Well this last Sunday she went up north to spend the day with her friends and later in the evening I planned a nice romantic dinner at home and cooked her favorite meal. When she got back home, she wanted to unload her vehicle and I told her not to worry to worry about it, that we'd do it later, and to come inside as she already had gotten home late so the food was starting to get cold. She had to get her friends stuff back into her vehicle, I ended up helping her do that and told her to follow me, we got to the top of the steps and said she wanted to wait for her friend to leave, and then while watching her leave she told me that it upset her that I wanted her to as she said "forget about taking care of her friend".

I snapped that I'd planned this whole night and was upset, sol turned around and just watched her friend leave and just didn't answer her when she asked me a question. We ended up going inside and while I was upset, she chose to get angry and start yelling at me because I ignored her while I was upset and while I was crying and telling her how hurt I was, she chose to walk away and refuse to talk to me, ruining the dinner and then decided to break up with me, ending our relationship because I got upset because she chose waiting watch her friend leave rather than come inside and enjoy the romantic dinner I made?

So tell me AITAH?
