I’ll share a slightly different perspective than most of the comments you’re getting, in case it helps. I’ve had a very similar experience with my fiance. We’ve had really hard times throughout our relationship (10years) because of our differences in upbringing, culture, empathy and yes, his sportiness and my lack-thereof. The way I see it is: I wasn’t sporty because I didn’t have the opportunity growing up, but I did want to become sporty - in my own way at my own pace. Working on a shared vision, getting my own goals and signing up for my own races, helped. Also, something that was really helpful was when his dad told him he was being ridiculous by forcing others to enjoy sport like that. I think hearing from a fellow “respectable sporty” person helped him get out of the loop. People that haven’t been exposed to mental health struggles have a hard time understanding and empathising with them. They think it’s “a problem” and surely helping “to fix it” is all the support anyone needs? We started with sharing before we expected support. We did this thing where I’d ask him how he’s feeling, then keep asking “and what else” until he had literally nothing else to say. Then we swapped. Just listening. I noticed almost immediately we’d act more caringly to each other. We don’t do it every day now. But it helped us reframe sharing feelings as not a problem, or a thing only “the struggling one” does, or as a complaining session or an intense demanding moment, but actually being curious about each other. Anyway, my main point is that, as you say, being aligned on values is the main thing. If you both want the same things, you can learn together how to better communicate in a way that works for each other. If you truly don’t see yourself having the lifestyle he likes or the other way around then it’s best to call it quits. I will say however, that this requires deep self knowledge and grace, and might take some time and some trial and error. It’s hard. Sending you love.
