Being injured [censored]. Especially during a time when you need exercice to make you feel good. I know how you feel cause i felt the same when i fractured my ankle last year.
Regarding your ex, i bet he is jealous of your life as a single woman that can date and go out and do what she wants without having to answer to any one. I would be willing to bet money on that.
You have a lot going for you ginger. And honestly, you dont need a relationship to be complete. Maybe view it as all these adventures and potentials... there is fun to dating as well no? Maybe refocus on that.
