It really hurts the lies they tell... I feel for you. My H told his friends, who I had counted as my friends, that I self mutilate and am crazy. They believed him and dumped me, accepting OW into their lives and circle - just like that without ever allowing me a chance to explain. (I cut myself when I was a teen bc some friends were doing it... maybe for like 2 weeks before I decided it was stupid... and that was 23 years ago, 11 years before I even met him and when I was a KID... it's crazy)
They really do say hurtful things and it's a projection of their own fears about themselves. Do not take it personally. I'm sorry you had to read those emails. My H also said mean, hurtful things in an email and yes, lied to OW also.
