I'm sorry, he got found out and then took TWO WEEKS to end it??!
Wtf, op?
This is not a man who loves you. I'm so sorry, I know you're heartbroken but actions speak louder than words here.
If he was so keen to end it with her why did he need to be discovered to finish it?
This is what the evidence shows: he has been in a relationship with and fallen in love with someone who means more to him than you do.
He has been with her for 2 years, showering her with expensive gifts and love and when you found out about he needed a full fortnight to end it (apparently- where is the proof that he has?)...The fact that it took him 2 weeks to have a phone call to end it even though his marriage has imploded shows that he values his affair relationship more than his marriage with you.
It shows he had to think about whether he wanted to end it at all (so he can't have been relieved to end it because when youre relieved you dont hesitate), and that the bigger deal to him wasn't his imploding marriage and the betrayal of his wife and daughters, but the prospect of ending it with the other woman.
You don't need anymore evidence to see what's right in front of you.
You don't need evidence of seedy trysts in hotel rooms or receipts showing more of his lies.
At the moment of discovery, he has shown you exactly how he feels and how much you and his life with you means to him.
He checked out of your marriage years ago.
He's nothing more than a lying, selfish coward.
I know this is an enormous shock and that your whole world has been upended. It will take time for you to begin to get your head around the depths of his deception and get used to your new reality and I know in the meantime its deeply confusing. This is why as you grapple to make sense of the last 2 years you need to focus on who is showing you he is right now.
Speak to a divorce lawyer, op. Get your ducks in a row. X
