"I'm not good at these things." Is that an acceptable excuse for not trying to solve his problem?

My (estranged) husband and I haven't consummated our marriage. We've been married for 8 years. The first year, he would not see a therapist with me. But eventually we saw three therapists over the years and as many doctors. However, I was the one who had to find the doctors and make the appointments and basically drive any sort of research into why my husband was impotent and what our options were. I'd ask my doctors, surf the 'Net, read, whatever for answers. I'm still not sure what my husband did except ask his doctors. It wasn't enough IMO. When I asked him, he said, "I'm not good at these things," e.g., surfing the Net, calling around to experts, etc. I finally had enough and asked him to leave. I didn't buy his excuse anymore. Would you have?
