Pelvic injury affected his sex drive

My husband and I been have married for five years and we have two children. We are both 30 years. A few years ago he was involved in a road accident that injured his pelvic area. This injury affected his libido and now he has no sexual urge. He has refused to seek medical help and now I am suffering because we are not intimate. My request that he sees a doctor infuriated him to the point that he moved out of our bedroom and now he sleeps on the couch. It is two years since we were last intimate and I can’t take it anymore. I love him so cheating on him is out of question. What can I do to solve this situation? I want to be sensitive about his situation but I also have needs. Please help
