WOW. Honestly? You dodged a MAJOR bullet with this one.

He couldn't see what was wrong with the big fat LIE he told, to begin with. Not only was it unconscionable to NOT tell you about the 3rd child when asked, but then to turn it ALL around on YOU, saying YOU'RE unreasonable for being upset about HIS LIE?

Consider yourself very very lucky that you did not have a child with this man. Good news is: you found out before it's far too late.

What he did is called DEFLECTION. He deflected onto YOU what was HIS fault, and made you feel like you're to blame for something irrelevant to HIS BIG FAT LIE. In other words, he turned the spotlight onto YOU. It's called deflection.

Don't absorb that crap. It's HIS lie to own and to take full ownership of. If he cannot admit that it was WRONG of him, GOOD RIDDANCE.

I wouldn't go back to this man after something as bad as that.
