I think people will come and go and stay with us until we learn the lessons from them. After 19 years of marriage, I too say "never" again. I am in a relationship that is truly helping me heal and grow. I don't have a destination and I hope we don't have to think or talk about what's next. I am happy in the hear and now, and will take it as it comes.
I am glad you chose YOU and life has its mysterious ways, so never say never. Enjoy your life and stay open to possibilities.
