It's totally understandible to me that you would miss someone with whom you have shared some satisfying experiences and pleasant memories. It's also true that people frequently make the decision to stay with a partner who is less than ideal. I guess it's up to each individual to decide how high to set the bar for what to expect in a relationship.

The things you've related about this guy make me feel you'ld be setting that bar awfully low, if you were to tolerate what he thinks is an okay way to treat someone. You'll eventually recover the function of your foot. But sooner or later, you are likely to encounter other health difficulties. Now you know how quickly he'ld run out on you, were you to have something come up that made you less "fun" to be with. Then the hurt of abandonment would start all over again. I, myself, wouldn't want to live in fear of that.
