Online dating cheat forums
Even if you don't know them all personally, do you know how your spouse knows them?
Indeed, some people aren't even sure online cheating is cheating.
It doesn't matter what the rest of the world thinks; it matters what you and your spouse think. Secrets about what you're doing and who you are talking to should not be happening between spouses. Once you're keeping secrets like this, you are putting your marriage at risk. Those who've already determined that online cheating is taking place in the marriage should see a marriage counselor or other professional to discuss the root of the problem and whether the marriage is salvageable.
A spouse who is suddenly extra nice or extra mean could be compensating for an affair.
One might be super sweet out of guilt or super mean in the hopes of justifying his or her behavior.
Whether either one of you is committing online cheating, you should sit down and have a conversation about what you feel is appropriate online behavior for married people.
