My boyfriend [21 M] ditched me [20 F] to spend time with the boys right after my father passed

My Dad unexpectedly passed away a month ago and I was the one to unfortunately find him dead, but that isn’t what this post is about. My boyfriend and I have been together for about 3 years. He has a full time internship so I don’t get to spend a lot of time with him.
Yesterday afternoon, I asked him what his plans were. He said nothing. I suggested that when he is off from work, him, his brother, and I should go bowling or to a movie. I figured including his brother who my boyfriend is super close with would make him happy. He said that he would like to do that and would contact me after he gets done with work. I based my plans around this and didn’t make plans with anyone else.
About an hour or two after he gets off of work, he texted me that he is drinking with some guy friends and can’t come see me. I told him that this weekend I really need him because it’s my first Father’s Day without my father. I also said that he should have just not made plans with me in the first place if he wanted to hang out with the boys. He didn’t respond even though he read these texts. I just couldn’t imagine doing this to him if he was in my situation. In his mind, he thinks that I don’t want him to hang out with his guy friends, which isn’t the case. I just think that he should stick to his original plans and maybe be a little more empathetic to what I have been going through. Also for context, this isn’t the first time this has happened. Even a week after my Dad passed, he ditched me for his friends when I needed him most. I talked to him about it then. He didn’t think it was a big deal, but apologized and said he wouldn’t do it again, but here we are.
Edit: Thank you everyone for the really kind comments and especially those who are dealing with a loss of your own. It’s really difficult no matter how long it’s been so know that my heart with you too. Just to update on the situation, I still haven’t heard anything back from my boyfriend. I haven’t texted him since. I’ve been spending time with family instead. I don’t know what I was looking for when I wrote this post. My boyfriend always tells me that I overact so it’s hard for me to tell if my frustration is valid or not. I have realized that what my boyfriend did was not okay and I have been thinking a lot about how I want to handle this. I do really appreciate all the love and quotes and beautiful advice I’ve gotten. It was so unexpected, but I am very grateful. I am going to try to respond to some comments as soon as I can. Xx
TLDR; my boyfriend ignored our plans to hang out with his friends
