Irritation I am Writing to Myself

I'm a bit irritated at the BF this afternoon.

I was very excited about having a weekend off, the few weekends I get off and he made a point that we would be finally spending a whole day together for a date. Something I look forward as well. Unfortunately that day, a pre-scheduled dance workshop by one of his friends and a great influence on his life is on the same Sunday.
In the beginning he makes the point that he would not go to the workshop because of my lack of weekends. I was conflicted hearing this, although I appreciated the sentiment. We argued a little about not having days off and we both understand that we are trying to compromise and make do with not having official "dates". He also made such a big deal of wanting a whole day off, something I wasn't as concerned with although appreciated the sentiment.
He decided to make a compromise saying that he would try to free his Saturday so that we would have the whole Saturday instead of Sunday, since he only had one lesson that day. With this compromise I was happy with and, again, appreciated the sentiment.

With this I am messaged again that his boss was unhappy with the idea of him moving the lesson so that Saturday was free and I understood that he would want to go to the workshop, therefore I was fine with postponing the whole day together and working around the workshop as usually as with the workshop there I do not consider it a whole day.
What irritated me was the fact that he continued to ask me if I wanted to go to the workshop and that him not going to the workshop was for me. I was unhappy with that. It made it sound like him not going to the workshop would then be my fault. The blame shifting as he tells the coach "Because my gf wants to go on a date, I can't go to your workshop." And that pissed me off. If he wanted to go then he should go.
Then he says that he's trying to prioritize me over dance and that irritated me even more when he says it as if I am forcing him to do something he doesn't want to just for the sake of making he happy. And frankly that made me more irritated. I am fine with postponing our whole "date" as planning around something is not what I consider a whole "date". Yes, it is still a date although not the kind of date I would be very excited about. And true, I am a little disappointed that the date will need to be postponed, but I rather postpone the date rather than postpone the workshop where it is more of a social and work obligation for him.

I'm a bit irritated that my view was not so much addressed. I don't mind the situation being compromised, although I am irritated that my views is not so much addressed.

[EDIT] Well... I'm glad he knows that I would rather do something completely different then half-ass a trip to SF. What's the point of going to the city if you can't fully enjoy the city for what it offers. Well we've come up with a conclusion which I am glad. Yay next Sunday.
