Why is he being so brutal to me?
The same thing happened to me.
They do this to either relieve themselves of some guilt. I mean if he is being an awful twat, you aren't going to be nice back to him. This is the only part that matters to him.... therefore you are being the twat in his eyes.
Or
If he is just awful enough you will leave him, and that saves him being the bad guy ..... the story will always be that you left him.
or
He can't accept that you caught him out in a lie. So his true colours are showing. Has he ever been put on the spot like this before, probably not so you don't know this side to him unfortunately.
But you will never know so there is no way anyone can answer the question. The main thing is now that you look out for you, you are the only one that matters now. Fuck him, he doesn't get to do this without recourse.
I wouldn't be posting stuff on FB or anything like that. He knows what he has done, the ow, well she may or may not know about you.
I am not going to say it is an easy ride ahead. But once you get through the storm, you will look back on this from a much better place.
And lastly, don't keep this all in to yourself. It is not your secret to keep. I felt quite shamed by by exs affair and didn't tell a soul. Just tried to muddle through my feelings etc. It was a big mistake, as I was still covering for him iyswim.
