I'm guessing the DH's who say it isn't cheating are the ones who I am constantly coming across on my Bumble app (dating app similar to Tinder for those who may not know). The ones who don't know how to edit their photos from Facebook, so you see the spouse in every pic. Sometimes even the kids. I always wonder if the DW's of half the guys on there claiming to be in open marriages would agree that they are also in open marriages. I find this far more prevalent here in the DC area (MoCo and DC proper are where I'm at mostly when I'm town) than anywhere else. I spend 2 weeks out of the month in the LA area and I don't come across nearly as many married men as I do here. It's seriously disheartening.

*he feel

Yes.
Te(Sexting) is a form of cheating.
2016 style.

If he is such a knuckle head to deny that it is, then how would you feel if the tables were turned and you did that while being in a relationship with him.

Pretty sure he won't be so eager for you to do the same thing!!!!

If you asked this same question on the explicit board the answers would be very different.

Doesn't matter what it's called. You don't like it so he shouldn't do it.

OP here. Sounds immature that we haven't talked, I know, but haven't you had arguments/fights with your spouse over what seems trivial/insignificant but it just stirred up so many emotions that it bled into the next day?

We have never discussed what constitutes cheating (now I know we should have!) but at least we started the talk. I just can't believe his take on this.
