Hi Kitty,
My Ex did the same thing. Went out night after night with many different women. He was only trying to fill the void of loneliness.
He still thinks I'm the key to his happiness if only he would seek the help he needs to understand and realize that his happiness lies within himself. Nobody else!!!
I get lonely too! When we first separated I went out alot so I won't think of him and my pain. Now I'm in a place in my life where for the first time I really enjoy being alone - the solitude. I love being with my children but the times I do get by myself I love.
Hang in there! When it's time for YOU to go out - you'll know and it'll be for the right reasons instead of the wrong. I'm thinking of you.
Love,
Galnva
