Why is my bf so distant

it’s like I was gone for a week to do sports right...he was apparently fine with it. I come back and he’s not even excited to see me, never said he missed me and leaves me on opened..I’m sick of him. Everytime he does his thing I’m supportive to him but he never returns the favor. I wanna break up with him but then I feel bad. I literally text him “hey babe❤️” and he leaves me on opened for up to 5 hours 🤦🏻‍♀️ I know he’s not that busy either
