An affair, sex, seeing someone behind ur back, kissing (if it's more then a peck).<br />
People flirt but it's when it moves beyond that & ur lover doesn't stop it, that matters the most. (like my ******* husband!)
If you have to keep something a secret, or lie about it, due to shame or fear of consequences, then that's cheating.
If you asked this, you probably are...or would you do it if your spouse were watching
Then it's cheating
Physically cheating, anything. I mean kissing or more. Hand holding, lap sitting, hmmmm I would be pissed if a significant other did any of that but I wouldn't be able to call it cheating.
Are you forced to marry him? If not, break it off.
That is sexual contact.
