Cheating is whatever your spouse considers cheating to be. Most people would consider sexting cheating. It's a fine line until you cross over to something physical. If you feel the need to sext do it fantasy based with your husband. If you have no interest in doing so than it seems like you might be the one that wants to leave.

You are dumb if you don't get that and he should flee.

depends...its an easy line to cross/blur

you are cheating

It's cheating.

you have your new romance already set up for when your husband splits.

Yes.
What if your husband was sexting with another woman. And you found out.
How would you feel?

Dear Postee, some people come here because they are dealing with real
life situations and complications. They are genuinely seeking to unburden
themselves, and perhaps receive advice which will help provide clarity, resolution or closure. 9am posts which are obviously fake should be directed
to other boards and forums.

1) what motivated you to engage in creating a record of this? What motivated you to engage in this behaviour at all? Quit trying to justify it as harmless.
2) if your husband feels that this is cheating then take it seriously-how he feels matters.

The fact you have to ask is pathetic. I'd drop you like a fkn bag of rocks. In fact this confession is sooo stupid, i suspect you're a troll.
