Dear Amy: I have been in a 20-year relationship with a wonderful man who has been there for me — through thick and thin. We raised my children together and are now enjoying our grandchildren. I have been very unhappy in the relationship for the last few years because I’ve fallen out of love with him. I don’t want to have the grandbabies lose out on a wonderful grandfather because he will leave the country if we split up, but I want to be happy, too. I’ve always liked women, but I didn’t want my mother to take my children away from me if I lived my true self, so when I met him, and we decided to get together, I honestly wanted to grow old with him. Now my children are grown, and I feel like I deserve to be happy.
