what a deluded twat. it doesn't have to be this way. so you are ending it then, thats it. and "I hope you are pleased with yourself"? !
Really??!! Is the man for real? Is he pleased with himself? for fucking somebody else and lying to you?! ooh, I am so angry on your behalf because he is such a total knobhead.
what the hell else does he expect. Is he going to run around saying "I made one tiny little mistake and she goes and throws me out"?!
My Xh walked out on me, then when i begged him to try again, he said - oh but you said it would never work now as you would never trust me again - . so it all became my fault obviously!
LV - (and I agree, that term belongs to your H not you) - this is your life, your decision. If you want to take him back, you can. You might think it is the easiest option. But it will kill your self esteem and it will gradually kill you. it would eat away at you and you would probably always be mistrusting. Thats what i think it would have been like for me anyway, if I had persuaded XH to come back. It would never have been right.
Just remember, no matter what he says, that it was him who did this to the family, not you.
If he needs reminding of that fact, then right it on a brick and throw it at his head.
