So she was like a second wife without a marriage license.
Lots of things you must investigate. At first we all wish to reconcile, but that's before we know the whole truth and before it all sinks in. It's impossible to reconcile without all affair information, without the big picture - and I mean really reconcile with love, caring and a true marriage. It's possible to stay together in an Icestorm kind of marriage of two strangers living in one house. But I doubt that's what you want. So your husband can get as pissed off all he wants, he can storm out and rant and rave and turn red in the face but you must insist on truth. Because in the long run you hold all the cards here even though he thinks he does, and you even think he does and feel weak. He doesn't. You'll grow stronger.
These questions I list below you don't have to answer here, to us, but there are things you may wish to know during this process. Also, don't bother asking him. He will just lie. You'll have to do the independent research.
How much money did he spend on this woman? Help her buy cars, condo, vacation money? Do they have a child together (you really, really need to do some quiet research on this aspect. There are reasons she may have for not telling yet, if there is one). Just because she says she won't see him again doesn't mean that she's serious. Just as you want to kick him out one minute and beg him to stay the next, she's probably doing the same. Everything you're feeling, she's feeling. If you miss him, she's missing him. If you want to live your life with him, she wants her life with him, too.
One person can't reconcile. If your husband's going through withdrawal from the loss of her, it's going to be rough on you. He will not wish to read information about affairs, because he probably thought he was so smart and smooth and you so dumb he pulled off the perfect adultery. Probably smirked every time he left the house. But you will have to show him that the process is long and difficult, and he can't escape it whether he chooses you or her.
Stages of recovery and marriage grief are inevitable, whether reconciling or splitting up. It hurts like hell either way.
Whichever woman he winds up with is going to be angry, miserable, question everything, distrust him and during the anger stage, tear him a new a*hole, though he seems to be so big of a a*hole already there may not be room for an extra one.
You've known him for nearly your whole life, and now he's a stranger. Awful feeling. We all know what that's like to some extent.
He's been wearing a "mask" disguising who he really is for the past 7 years or more of your marriage. He's been an actor in a role. Often, the man in the mask can't bear to face his own exposure and have the spouse see who he really is behind the mask, and that's why he's angry at you. His life was perfecct with double nookie double fun and you ruined it.
So I suggest you hit the anger stage quickly, because you'll learn that the more we cry, the less sympathetic the WS will be.
