My long distance boyfriend (22M) decided to spend majority of January 1st with his friends and I (23F) am hurt and upset. How do you let go being angry without confrontation?

It's January 1 and my long distance boyfriend (22M) and I(23F) barely talked. He went to go have lunch with his friends the whole afternoon which I don't mind by the way because I love looove seeing him happy and he would update me and answer my calls if I ask him to. I'm just a little sad because he got home and started playing (which normally Idm because that's something we do. we go in a call and do our own thing) but then he told me he was gg to go in a call to play with his friends when we barely talked and I'm assuming that he's gg to play the whole night.

I specifically told him last night that I wish we could spend time today because I'll be busy after January 1st. I did not tell him the part where I have to work on the weekends because I'll be visiting him next month and I kinda have to make up for the days I'm not at work. I literally have to work everyday after today for the whole month of January just so I'll even be able to go on that trip.. I didn't want to tell him this fact because I didn't want him to feel bad but it does weigh heavy on my chest. I don't plan on confronting him or making a big deal out of this because it's the last thing I wanna do on the first day of the year. I'm just scared I wouldn't be able to stop myself from exploding later tonight because I also don't think he deserves it. :")
