I need validation. Self esteem at an all time low.
The worst thing for your mental health right now is for you to seek validation from others. The worst thing we can do for you is to give it to you. You have to validate yourself. You have to believe that you have worth. Someone you love is rejecting your love. It happens. It doesn't mean you don't have worth. It doesn't define you.
You have ZERO control over how your wife feels or what she does. What you have 100% control over is how you respond to it. Find your anger, find your strength. Don't be anyone's doormat ever. NOBODY respects a doormat and nobody can love someone they don't respect. Be brave. Validate your own self worth. Have courage. You can do this.
