Cindy,
Your post struck a very familiar chord with me. My dad was fiercely independent, pretty much to his final day. It worried the hell out of me. For the longest time he insisted on driving himself to treatment, etc. I was always afraid that he would get into an accident. I had a habit of being close to the hospital each day he had treatment just in case he didn't feel up to driving home. I know it sounds neurotic. I wanted him to have his independence, but I also wanted to be close by if he needed me. I never told him that I positioned myself within a mile of the hospital, but I'm glad I did. It gave me peace of mind. Also, the day did come when I got a call from his treatment nurse asking me to come and drive him home because he wasn't feeling well. It was tough for me, but he wanted his independence and it took me awhile to understand that. I think all care givers go into "over protect mode", but it made sense when I realized that he wanted to try to live life as normal as possible. Perhaps that's what your husband is doing. I'm sure it's not being done to leave you out, and you certainly are needed and appreciated. I'm positive of that. He's an independent guy, you can't fight it.
Regards,
D
