should I be mad?

So me and my boyfriend have been dating for a long time now and he is constantly telling me about how he wants to marry me and how I'm the love of his life and his soul mate etc but every time we like plan a weekend trip or have special plans he always cancels last minute because he has soccer practice. It happen all the time and it sucks cause Ik how much he likes it but we had plans that I was SOOO excited about and it's not like it's a one time thing it happens all the time. I love him so much and I put him above everything else because he's my number one ans we are ant a future together but i just wish that for once he'd make me his number one and stick to our now plans over soccer. Would you guys be mad if your bf kept doing this to you?
