I like bernie's comment....

But, I know it's hard to take the high road. But, you'll be better off in the long run if you do.

And... The name of that type of guy... plain and simple. A$$ho!e

And, seeing that I rarely if ever swear... that'll show you what i'd call him.

So far I like most of it:

"A$$ho!e"
"An opportunistic fuck"
"Nothing but evil, deceitful, and adulterous. He is like a virus; no medicine can cure him, just moves from victim to victim. "
"Untrustworthy comes to mind, so does pathetic but "a disappointment as a human being" sums it up better."
"No good, dirty rotten, slime bag, mother fockin', son of a bitch, next in line for the shot, scum sucking, bastard."
"man-whore"

a douchebag degenerate...but it takes two.

Since you're working on your marriage I would call him a bastard and open up a can of whoop ass or at least hint at it.

you call him an undertaker

I like this one "low life son-of-a-bitch spineless coward sissy boy"

I know the guy who got involved with my wife, has kids my age and his wife cheated on him 5 years ago. He is divorced now. I thought how could anyone who has been through it do it to someone else. They are pure idiots. I phoned him(obviously he didn't answer.....they are cowards), so I left this message:"Hey Paul, I bet you hated the guy your wife cheated with, well guess what, now your him. Good job." I don't know how he reacted to it, but it made me feel better

Asshole...sorry!!!

So - I thought things were better for you?!!

Fucktard? Scumbag?

How about if you just pound him and don't call him anything?

mother fucking slime bucket man whore

I remember when my husband cheated on me. I so wanted to destroy that woman.

But I knew, deep down, that my hatred and rage was not about her.
She could not have succeeded if he was not interested.
And he would not have been interested if his needs were being fulfilled by me.

It was really hard to look at myself in this pain, but I did.
And we talked.
And I found out that I was letting alot of things slide.

It is always easiest to focus on the "other".

But it never really accomplishes anything.

I know that this is not what you want to hear, but what we need to hear, and want to hear, are usually very different.

I am sorry for your pain.

An Fuck head, A low person

Why do you need to talk to him? Instead of thinking of insults to sling or labels to paste on him....kill him with kindness and grace. Don't indignify yourself by trying to tear him down.

I call him a male whore, or just pathetic and desperate.

I told my no ex to make sure that we never met.

The guy who pursued my ex was also married. You have no idea how bad I wanted to hurt him. I almost hired a PI just so he could go tell his wife that he was humping my wife.

I just call them narcissistic assholes.
