Distant boyfriend

I’m 15 and me and my boyfriend of the same age have been dating for 9 months already. 3 months ago before basketball season began, we were close, he’d always text me, we FaceTimed every night and we always hung out, but ever since basketball he’s not like that anymore. Barely texts, never calls, we never hang out. I understand he has practice every single day but it kinda hurts when sometimes he has time to hang out with his friends instead of me. I posted a cute message for him on Snapchat and he opened it and didn’t respond and it kinda made me sad. I don’t know what to do. I know he loves me and I love him too but I want things to be back to normal and I want him to seem like he likes being with me again. Please help.
