I understand about having to do everything on my own, but I don't allow myself to become resentful. It serves no purpose. I don't expect any help from him, so I'm not really getting let down.
I don't take him on any camping/hiking trips with me. For one thing, it's a liability. When we're canoeing or hiking in remote areas, it just wouldn't do to have someone drunk because it's downright dangerous to everyone.
I just got done planning and organizing my daughter's wedding all by myself. Everything, including the tent/table/chair rentals..to the decorations, the dj, the caterer, the dress, the venue...he didn't help with anything. At least I had my other kids to help out and I got high praise for being able to do it all despite all his efforts to drag me down.
