Say something or no...

My boyfriend is a local artist, and because of this, his schedule is full. Since he's preforming most nights, we have set date nights twice a week (usually on Monday and Wednesday) He put out a mix tape last year, and while he was working on it, he was CONSTANTLY forgetting date nights. Now I tried to be understanding, and didn't complain until it became weekly. We compromised and moved on. Now a year later we are back in the same position. Last Monday he forgot, and Wednesday he had a studio session. Both days I agreed to move date night the day after. This weekend he was supposed to help me move, but was nowhere to be found because he was in the studio. -___- now tonight was supposed to be date night and he didn't tell me he had to go to the studio until today. I don't understand why tf he has to do his studio sessions on the 2 nights a week we see each other. Should I bring it up when he calls me tonight?
