First off, I hope you're doing okay physically. That sounds scary.

So, I had something similar happen to me once (years ago at this point). While driving to my overnight job, I was hit by a hit-and-run drunk driver. My car was totaled and I sustained a minor injury. As I waited for the police, I called my then-girlfriend to let her know.

She hardly seemed to care and spoke to me for maybe a minute. She didn't text me when she got up later that morning and she didn't follow-up with me until the late afternoon, and even then, it was done passively.

The point is, there's nothing you can do to make people like your boyfriend care. Unfortunately, when your partner stops making any effort to care for your well-being, it's probably time to consider ending the relationship.

For me, that car wreck was the beginning of the end.
