I’m pushing him away, help me save my relationship

My boyfriend has a lot going on so we’ve been spending a lot of time apart. He has football every day and work every night. He canceled our vacation to see his dad who he never sees. He’s late when we have plans because he has other things to finish up. He’s been unintentionally not prioritizing me. And I’m really taking it to heart. The past 4 times we’ve seen each other I’ve either cried or yelled at him because I’m so upset. Now I don’t even think he wants to see or deal with me. I understand I may be overreacting but no one can tell me how to feel. I feel upset and angry. I miss our relationship. It doesn’t even feel like a relationship anymore. And it’s partly both our faults, but I want to take initiative to make it better. I was hoping he would but he hasn’t so I have to or else we’ll fall apart. How do I get us out of this hole? Any advice is appreciated.

PS try to refrain my negative comments, I know I overreacted a little because of my emotions, you don’t need to tell me that. Just advice pleas
