Hi Nit, hope the dishes get done, it does seem mundane but if we can have our living area's clutter free it does help with our mood and feeling of being overwhelmed.

Set yourself very small tasks. Be tolerant of yourself, this will take more than a few days to get over--BUT you will. Try to block the thoughts but if you really can't let stop them,let them come but try just observing them like an outsider would. Allow yourself x amount of time to weep etc then stop. Start a new chore or whatever.

Let your xh go, pray for him from a distance if you want to like BND says. For now accept he is gone from your life as in being your husband but one day you may see each other again, we have no way of knowing. Far far too early to even contemplate that.
You are the most important one now. The less you hear about him the better.

He made his choice, you may not agree with it, you and everyone may tell you it is not a good choice and that he's not happy or his m won't last. That is not your concern, it will keeep you trapped and afraid IF you go that route.They are probably trying to make you feel better but ultimately it feeds you false hope.
Don't let thoughts of this man and his marriage rob you of anymore of your life and happiness. You deserve so much more than a coward who hadn't the common decency to tell you.

People can say it's his guilt etc, tell them to stop for it is not your concern. It will keep you trapped.

I know you will not feel like going out socially, but try to walk the dogs maybe and just soak up the goodness and beauty of your surroundings. Watch a butterfly simple pleasures, smile at strangers.

Make yourself a simple meal but maybe set the table for it with a single flower,any of the earths simple beauties will help to restore your soul.

Sending you hugs. Hope the blood tests results are good.
