I am so sorry for your loss. I know what that feels like. One year ago yesterday I lost my husband of almost 50 years. We fulltimed the last 15 years of his life. We had just bought a home in Florida as he wanted to start snowbirding and using Florida as a base since our son lives there.
We had 2 motorhomes. A 40 Phaeton diesel pusher and a 22' gas B+ (which we bought to take to Alaska). We had kept the little one because we loved it and planned to do some older state parks where smaller is better.
I had always driven both, so it was no problem. My DH died on the road, so when I got his ashes back, I drove back to Florida and emptied the big rig out, cleaned it inside and out and sold it within a 6 weeks. I kept the little one.
I joined a Women's RV group, the Florida chapter, hoping to continue camping with like minded individuals. A lot of members are widows who wanted to keep on camping like I did. It has been a good experience and a healing one at that.
It is different being on my own for sure. But I am trying to continue to enjoy things we used to do together. I was not content to stay at home after 15 years on the road. I am currently in Indiana in my little rig due to the death of my Mom. Her funeral is tomorrow, then I am heading south once again.
Best wishes to you.
