BF troubles

But lately I feel as though he doesn't need me or want me. 

He never ever invites me to hang out with his friends, like I get people need their alone time, but this is all the time. 

He recently joined a mix team sport (boys and girls on the same team) and he didn't tell me he was joining a mix team let alone ask if I was interested to play. 

He never organises dates together, he doesn't tell me how good I look if I dress up all nice, if I ask him to hang out with me he always says "doesn't bother me, it's up to you" like I want him to make a decision for once. 

He never used to be like this. It's like he's just given up or bored of me. 

He suffered a knee injury a year ago and he's been out of sport. He's a very sporty person and to not be able to be active like he used to. I feel as though he's slightly depressed because he has to gain back the strength in his leg, and because of this he's bored and feels as though he can't do anything, it didn't leave him disabled or anything but I feel like it has affected it him negatively and unfortunately he is losing faith in our relationship? 

I'm not sure what to do. Thank you for reading through my rant. Any advice to help him would be appreciated x
