You think he's tired of me?

So I'm seeing this guy for around 4 months. he said from like 1st month that he was my boyfriend. But we haven't we haven't meet eachother's friends or family yet.

I've had knee surgery a month ago. It was programmed and he knew from the start that this was coming. I don't know if maybe I expected too much of him, cause we haven't been dating that long... But he didn't go see me at the hospital. he said he didn't want to run into my family, which I get, it would be awkward since they don't know we're dating, but I didn't see him for a week after I got discharged, and it pissed me off... And now he seems to be avoiding me a bit. I see less of him and always seems that I'm the one trying to make plans... I know I'm not the most interesting person to talk right now, with being stuck at home and limited mobility and the pain, etc... and maybe because of all that, I'm too sensitive and misread things... but he seems to prefer to stay at home doing nothing instead of coming here to stay with me... And when we see eachother, he seems to be a bit distant, not a lot of kissing, just cuddling - and I know I can't have sex because of my knee but we could do other things... I'm worried that he's getting bored with this relationship. Or maybe it's just in my head, cause I sort of expected this to happen. What do you think? Thanks
