Hello Takingitdaybyday, Glad you found us here. You literally do have to take it day by day. Your feelings and emotions will be all over the place. Betrayal and deceit by the person you most love and trust, is a life altering event.
I struggle with thinking about what my H said to the OW, what they shared. I was never a jealous person but it kills me when I recall what the OW told me, that they loved each other and that I was in the way.
Many of us lose our confidence, lose weight, lose sight of who we are, lose direction, cant sleep, cant focus, feel down, feel depressed, feel angry, feel hurt, feel hate, feel lost, feel isolated, feel that we will never be the same person again.
You cannot put a time limit on trying to "get over" what has happened to you. You have suffered a trauma so take all the time you need to recover.
Your H seems to be doing all the right things. It will take time for you to start trusting him again. Have you taken a look at the Healing Library? Lots of good reading there, keep reading other people's posts and you will see that you are far from being alone.
