@Lf803 your DH sounds quite horrific. "The truth hurts"? Jesus Christ, that's his dickhead opinion, and its only purpose was to hurt you, and make himself feel better about abandoning his children.
I am not at all surprised you suffer from anxiety!
Can you imagine if your DS spoke like that to a woman? Or your DD lived with a man who thought it was acceptable to speak to the mother of their children like that?!
You would be horrified.
Your children are better off, not exposed to a man who has so little respect for women, and treats them with such contempt and dislike.
Whilst you are dealing with hurt, fear and rejection, you won't see that your DH has done you a massive favour. Take your day hour by hour, stay busy, and try not to dwell too much on his hateful words.
Rally your friends and family around you for the next few days/weeks. Ask your best mate to stay, so she can take your phone out of your hands if he realises his massive fuck up and tries to return. Bolt the door and start planning the rest of your life without him.
Today is the first day of the future you deserve. You've got this!
