Are there any health related deal breakers for you when it comes to a possible future partner?

I’m certainly not the picture of health but I do make an effort to see a doctor regularly, exercise, etc. I am overweight and I don’t eat particularly well…so I’m not sure how picky I should be.

There’s someone I care about a lot that I think could maybe be a good long term partner but he smokes (is trying to quit), is quite overweight and doesn’t exercise.

I don’t care too much about people having some bad habits but at what point is a bad habit a red flag? Though I know that growing old with someone will involve some taking care of each other as our bodies change…I also don’t want to be caring for someone super young or bc they didn’t take care of their health.

What do you think? Where is the line? Are there health related markers/factors that would be a deal breaker or a red flag for you?
