Yes, it is easier said than done. After all, you've been together for a very long time and moving on to something new is very hard to think about, much less do.
Good for you! Doing something for yourself, without him, is a good thing. It doesn't have to be anything as big as driving 400 miles, but it's nice that you'll be doing something fun. :)
Has someone suggested the book by Melody Beatty entitled "Codependent No More?" It was an eye-opener for me. I realized that growing up in an alcoholic home had made me very sick too - living with an alcoholic tends to do that to us. We are so filled with anger, fear, and resentment. We want to control things and want things to happen our way. The end result is throwing things and misery. I used to throw shoes and books - it was not a pretty sight. I also suggest Al-Anon. Best wishes!
What are you doing to take care of you?
baby steps.
Wow, you are making steps.
I can't remember if you have tried AlAnon, but that might be a move also.
We are here for you!
