Hi Garangy, When I first mentioned my desire to walk the Camino, my husband wasn't full of enthusiasm. Not negative. Just not enthusiastic. I was to travel with my daughter (thus the picture here), but a sudden change in the health of this until-then very healthy man prevented us going at the time we had chosen. The following year, he had recovered and I decided to head off ... this time on my own because my daughter couldn't get time off. That's when "not enthusiastic" shifted to concern. (He had taken comfort in the fact that if anything happened to me, my daughter would be there to make sure I was well cared for.) As time approached, and here's the happy part ... for my birthday my husband said he wanted to buy me the knapsack I would need ... and then a silk sleeping liner. The time for departure arrived (September 4th of last year) and off I went with his blessing. Like your husband, though I am not dealing with illness as you are, he was concerned for my well-being. But all went well. As others have said, you will be cared for. That's one of the many beauties of the Camino ... the kindness of strangers. I experienced and heard so many stories of giving and receiving care that they continue to warm the heart ... five months after returning home.
Some folks have mentioned the possibility of linking up with your partner at some point along the Camino or at the end. I met pilgrims who had made those arrangements and it was a happy scenario for both. Others had made those arrangements, but in quiet moments once on the Way came to realize they wished they hadn't. For me, I met my husband in London. I predicted (and correctly so, as it turns out), that I would want and need some time just "be" at the end of the journey.
A sad piece, for me is that my husband didn't stay in touch with me as I walked. He sent just a couple of messages during the five/six weeks I was away. I know now that he was reading my blog, but that didn't translate into meaningful messages from home. He offered an explanation when I asked him about this upon my return, but a sadness remains. I share this personal piece with you because it was my reality ... and, I believe, the reality for some others. Though certainly not all! Some spouses were "there" ... albeit at a distance of several thousand miles away. The more important piece, though, is that he did send me off with love ... knowing that walking the Camino was very important to me. And for that I'm grateful.
Hopefully, your husband will come to accept and understand your desire to walk ... but perhaps not. But if it's important that you do so, and it sounds like it is, I wish you well in offering him assurances that, based on the experiences of others (men and women) who have walked alone (or, at least, who have started off that way), you will be in the company of kind strangers who will do whatever they can to ensure your well-being. It may get a little tired hearing the saying "the Camino provides" ... but it truly does. Wishing you a wonderful journey ...
