She already has one foot out of the marriage. Take the dna test and present the results with divorce papers.

Argh, I need an update but it’s age locked and I don’t have the app. Can someone else check?

I'm with the commenters asking about Jas, and a part of me wonders if she's the one to actually put this idea in the wife's head. Maybe she has a secret thing for OP and is trying manipulate the situation? Idk. If she did, she's a sick, sick person and certainly not a friend, but if she didn't what reason would OP's wife have to think she'd consent to this cocamamy idea anyway?

The thing I find really wild is this idea of open phone policy to check on each other, ring cameras to check on visitors, tracking apps to check location. None of that is what trust looks like. I trust my partner unconditionally, and don't need any of this paranoia-inducing, spy-normalising technology to do so. (I have him on a map tracker in case he gets into trouble while walking in the hills). But also, if he asked me for a paternity test it would be game over.

Dude needs to realize there is no winning scenario, test or no test.

This is fake. What does "Jas" have to say about any of this?

It sounds a bit like the wife is having some sort of mental breakdown and paranoia attack to accuse with nothing else going on

I find it Odd that he dosnt adress Jan and her thoughts and opinions on this at all.

The why is the most important thing here. Is she projecting or become paranoid? Or has Jas or someone else hinted he is the father? Did she receive a poison pen letter from someone? A little more digging is needed before moving to divorce.

I'd say in this case you have already lost your marriage. And as for cheating? Sometimes with all the clever IT solutions, they cheat on you in front of your trusting naive nose. And then they also take away all you have too even if they have never contributed to any of it. So, my advise is, document everything for the family court and divorce her. you'd not want to live with someone who could not trust you even when you're so open with her. My current wife is the one who have opened my eyes on what is being a gentlemen vs what is being used and tossed. Trust, communication, love these are all two way streets apparently.

Like many others said, I'd agree to take the test but when it comes back negative she's signing the divorce papers. I agree that I wouldn't take the test but him arguing so much about his "integrity" is weird and makes this seem fake. Personally, my "integrity" would be one of the last things I'd care about, with the trust my wife and I had being first and foremore. I'd feel betrayed more than I;'d feel like my iNteGRiTy was at stake.

Maybe she’s just done with him and looking for a way out… my policy on this is that he can have a test but only if he also has a divorce. The trust is gone, time to pack it in.

Plot twist. She's in a lesbian relationship with Jas... and this is their bizarre plot to have you fund their love child. Did your wife steal your sperm in a used condom?

From an always try and restore the marriage frame of mind. I would advise taking the test to reassure the wife and then presenting the results with a suggestion of couples therapy to understand why she thought he would cheat and to resolve the apparent insecurities.

She’s looking for a way out of the marriage. Or she’s cheating on him.

I hate that everyone is saying "take the test and give her divorce papers" How long has OP's wife known Jas? If she's known Jas years longer than she's known OP, then Jas has some SERIOUS pull with what she can tell OP's wife and have her trust that Jas is telling the truth. I think Op is asking the wrong questions. I think he needs to ask his wife is Jas is saying he and she had intimacy If he serves divorce papers, it's because Jas wanted this relationship to fail for some reason.

Leave. Tell her where to stick it and leave her. Or kick her out, depends on who owns your current home. Better be you - kicking out is less exhausting than being kicked out.

Probably the "friend" said something shady to the wife.
