No mind numbing meds needed - just a game plan.

He calls you instead of OW by accident from his secret cell phone. He has an alternate email addie (just wondering, how on earth did you find this?)

He's not wearing his ring.

So - right now his behavior is not appropriate for a married man.

The question is, what do YOU want to do with this information?

Options include:
1) Confront - knowing this may push him out the door, but would relieve you from the agony of living with this uncertainty. You may want to consult an attorney first, get a good handle on your financial rights, before you do this. You also might want to find some way to squirrel away a little emergency fund.

2) Act As If - pretend you don't know in order to focus on winning him back by being so fun and fresh that you are way more appealing than the OW (who is probably nagging him by now, why hasn't HE left HIS marriage yet???)

3) Boot him. Just kick him out. Tell him you don't deserve to be treated this way and you are done.

All approaches have their plusses and minuses, only you can decide what's right for your sitch.
