I completely agree. Knowing now what OP has omitted, I find the rest of his post suspect. I'm guessing that the wife would have quite a different view of their relationship and the reason behind lack of intimacy.

I was dating someone who I really loved and trusted, but I started getting icked out. I thought it was a me problem, because as far as I knew at the time, nothing in our relationship had changed. I just felt gross and anxious when he touched me, and the feeling grew. I felt like I was losing my mind! I told him that I was dealing with some complicated feelings, but it was really hard to articulate what the issue was because I genuinely didn't know what was going on. I ended up breaking up with him because of it.

Turned out, he'd started cheating on me. I didn't consciously see any signs of cheating. No sudden weirdness about his phone, I didn't catch him in any lies, but the first time he slept with the other woman was the night that I just couldn't be around him without feeling gross. It all lined up later once I found out the truth.

Now, obviously, the wife in the post ( if we can trust OP as a narrator, especially now knowing he has omitted important details ) is giving reasons that don't seem to make sense. It makes me wonder if that's done by design to get a certain reaction from us here.

Should she communicate with him? Definitely. Has she? Hard to say.

That was absolutely my guess as well!

Wow. That changes EVERYTHING. If she knows, suspects, or has a weird gut feeling..then her being grossed our sounds less like potential PPD and more like she's over his shit.
