Same with me, My husband is a very good person, but as a married couple, we went wrong, deep down I knew, and yes it was a shock when he told me.
Trust me your emotions are all normal, you will hate feeling like this, and have no control of yourself. and the fact there is the OW, makes it doubly hard.
I felt like a zombie for days, did not go to the gym, or public areas, because for no reason I would just start crying.
It is a terrible feeling, I tried keeping busy like everyone says, it helps a TINY bit, but while running or this or that, you still think of situation.
Time is what you need, do not fight these emotions, lock yourself in the room and cry till you can not cry anymore, let us read about your hurt and anger. Dont keep anything to yourself. I kept a diary on everything, so when I could not sleep, I wrote, just get your emotions out.
I think that is what helped me heal so quickly and just come to accept it. Dont get me wrong, I hate seeing happy couples together now. So I am not fully healed, I still think of a few things. But all that horrible emotion you want to get rid of , does go eventually.
Also depends alot on what kind of person you are, on how quickly you heal. I have never dwelled on things, bad things happen I accept and move on etc, that is why when I could not get over this as quickly as I wanted to, it shocked me, I felt weak. But realised I had to go through it all, to totally accept it.
I hope you feel well today.
Keep me updated
