DU - Please give yourself the gift of time. Please do not make any rash decisions. When you do that the outcome usually ends up hurting you more.
Have you really thought this plan out well? Have you listed the pros/cons of this for you? If you give everything up to your H will you have the resources available to go somewhere and start over?
DU, you must think only of yourself at this time. You're coming at this out of pain and emotions. You would be trying to do the same thing your H has done. Trying to run from the pain and it will not work!
If you think of this as a selfless act to your H as your last gift to him he will not view it that way for a long time, if ever. In the mean time you will just add to your suffering. You are worth way more more than this DU.
I truly know what a big hit to your self esteem this is. Please step back and start by loving your self first and then the healing process can begin. You will then be able to think more clearly and not make decisions that are fueled by pain.
You can get through this. Give yourself the gift of time.
