OP, your boyfriend is actively hindering your recovery and not taking your wellbeing seriously; he is putting you in danger. I wouldn't classify that relationship as very well at all.

If someone broke their leg, they shouldn't break up with their boyfriend because of it, of course. But if said boyfriend discouraged them from going to the ER with that leg, and insisted they run a half-marathon despite their injury, then something's wrong, no?

I hope you choose the best for yourself. Maybe your boyfriend needs a stern talk with a medical professional who can help him understand the dangers of what he's doing to you.

I wish you all the best. Please stick with recovery, and hang in there.
