Check his phone.

You shouldn’t be in a relationship where the other person is violating your boundaries. It’d be best for both of you to get counseling. His sex drive is not going to decrease until he’s much older. You two are sexually incompatible.

Dump her. This is violating a boundary that should be apparent and she knows it.

I’d say I’m not going to be friends with a despicable person. And wish him well with the rest of his life.

She lied. Is that what you want in a partner? Dishonesty?

Certainly. I think the relationships you’ve thrown out as anecdotes simply won’t work in the long run. And taking back a cheater is 99% of the time a mistake. Because cheaters don’t stop cheating.

I think in order for this to work there has to be a level of scrutiny most adults don’t want and don’t have the energy for.

She’d have to give complete access to her phone at all times and location at all times. And respond to text and phone calls immediately. And if she ever goes radio silent or disappears for “me time”, then the relationship is over.

It’s too much.

Then you get into the notion of balancing the scales. Every time there is a fight or resentment well she cheated. So she’s always wrong.

This isn’t a just a mistake. Cheating fundamentally breaks trust. Whenever she goes somewhere or is texting too much, his first thought will be is she cheating again and lying to my face?

Doesn’t every branch warn the folks in bootcamp this will happen?
