do i have a reason to be mad??

Olivia
me and my boyfriend have been together for 9 months. our 1 year is in august its far from now but my boyfriend just told me that we cant be together for our 1 year, we had to do this for our 6 months were we celebrate it a different day or weekend. when he told me that he was going on a yacht with friends and his dad. he can back out he just doesnt want to. he does this twice in the summer.  and all the weekends in august he is packed with sports and mini vacations. and during the week he has two football practices a day for 2 hours and they are at bad time so we can't celebrate or hang out the month of our one year. am I overreacting? (also we had a date planned since September we would see finding dory opening day;hes going on a trip with friends. then the last day of school when we graduate he is hanging out at a party without me, AND new years we had plans and he ditched me for another party). please help !!
