YOur H sounds borderline sociopathic... YOu will have a VERY HARD TIME resisting him if he does contact you... You need to find yourself again...

When people marry the me/me becomes a we... when they separate you have to work hard to find that me again in the we.. Your H thinks he will find it with this OW, he won't... Affair couples success rate is less than 1%.. it won't last, I promise you that.

Don't name call or trash him no, but DO tell the truth. Tell them he was cheating, tell he gave you an STD and made a terrible mountain of lies and excuses for his behaviour and when you stood your ground to fight for your dignity he turned ran out.

Tell them you love him and your marriage and you refuse to tarnish that by name calling, but you will NOT HIDE his bad behaviour for him.

If you keep reasonable, dignified, and friendly to the community, HE will be gradually disgraced...

Don't send nasty photos or anything like that, it won't help you. it's just going to invite him to do the same back to you.

Find the me in there again. If he is indeed telling friends he's coming back you tell them you wont' accept him back... He needs to EARN it... he needs to divorce bust for a while if he wants back in.. he has to EARN his marriage back by working...

You set him straight if you see or hear from him... and you set these people straight about all the lies he's spreading around. Not mean, just state the facts and stay calm and friendly...
