OM a threat or just a friend? WAWs got an answer?

[Mr GK]

Yeah, what do I do? He met my wife online last yeat when I was neglectful to her.
She was lonely. She met some others online too. Some were good ladies and men, but some were men up to no good.
Some broke her heart, because they gave her attention and moved on to others.
Some were more sexual, and wanted to go that route online, and one time she admitted that she let guy tell her sexual things and as she listened she got to liking it.
she was more of the passive participant, but her body liked it.

ANyway, she put that behind her except for meeting this new guy.
He gave her attention. They talked on the phone, once for 3 hours. She said that he is just a friend. Actually he seemed to talk the most.

Well, after my wife decided to move up out of state, over 3 hours away, she decided to stay there with her sister, and her sister's 5 kids.
Shortly thereafter, he moved up there. He was going to move to california. He lived on the east coast. He now is friends with my wife and kids, and her sister and her sister's kids.
He has spent the weekend at my wife's family farm with her dad.
He has even visited my wife's grandparents.
Now that my wife's grandfather is in a long term care facility, her grandma is having a big garage sale.
My wife is going up there to help with that, and my wife's grandmother invited this other guy to come help.
He has worked his way into my wife's family's wife.
Yet he is just a good friend....who slept with my wife!

And the funny thing is that my wife and I are on good terms. We get along well. We just got LS. but we get along well.
She knows that I don't like him there. She likes that I am growing up and dealing with my problems. If the OM was not around, things might be easier.

Is he a predator?
What to do, besides, trying to be more attractive to my wife than him?

Is he just being a fake?
Will he hurt her too?
