Even with DNA proof the child isn't yours, that doesn't prove you didn't cheat. You can't prove a negative, and now that it's clear your wife thinks you would/have cheated, it's only going to escalate. She will see signs of cheating in other situations. The trust is gone, and you should end things. The relationship is heading that way and dragging it out will only be more painful.

Of course OP is the father, it's obvious, both he and the baby have a nose.

Maybe the wife is cheating with Jas

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.

What a weird way to tell him she wants out of the marriage.

She wants out of the marriage.

There is so much left out here. Why does the wife think he cheated and what did her friend say.

I'd like to know if they've been trying to have kids and can't. Because if so, this could be her struggle with infertility and inferiority by believing her husband is able to have children and she cannot. There's clearly mental illness involved here.

This one is weird.. they both seem childish and have some serious trust concerns. If this is real and he's really saying "by taking the test Im admitting to cheating" hes as irrational and stubborn as she is. All that talk aboit lying in bed awake lol.. these two probably fictional characters are too alike. Writing needs better balance

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.
