<human>: Could you distill the essence of the text into 1-3 sentences?

I'm 20/F and my boyfriend is 22. We've been friends for almost 6 years and we've been dating for 2 years.

Basically, the story is that his whole family has known for the past few months that his grandfather didn't have much longer. We found out he passed on Friday. This is his first grandparent death. We live in California but we don't live together. His family is in Colorado and so the funeral will be held there. He's flying out the entire Memorial Day weekend (which is also the weekend I turn 21) to be with his family. He only wanted to go to the funeral but family pressures are keeping him there the whole weekend. Because of my school, I can't go out to Colorado with him, or else I would have.

I know this sounds super bitchy and self-centered that all I can think about is me, but we've been planning to celebrate my 21st together for the last 3 months or so. This is because up until 7 months ago, we were in a long distance relationship and because of school, he was never able to be with me on my birthday. I know that he is upset that he can't be with me but for some reason, I'm still just mad. Not at him, but at the whole situation and that makes me kind of an aloof and distant girlfriend at a time when I know he needs me. I'm not flat out ignoring him but I know I could be more supportive. Again, I know how awful this sounds which is why I never mentioned up any of this birthday drama with him. These are only my selfish little thoughts. How do I push all my personal problems aside to comfort him? 

Also, another problem is that my schedule gets busier after Memorial Day weekend up until I leave the country for an 8 week internship... and celebrating a May birthday in August isn't really high on my list.
<bot>: My boyfriend's grandpa died. His funeral is on my birthday in another state. I'm secretly angry. How do I make the best out of this shitty situation?
