Hey Barry. Boy, your head must be spinning right now. I actually didn't realize that your DDay, or at least when you signed on here, was just 2 days ago. Thank you LifeisCrazy for pointing that out.
So, first let me say that you are doing extremely well for someone in their first few days.
Second, there's an SI saying: take what you need and leave the rest. Basically, you're going to continue to get a whole bunch of posts of all stripes. Sometimes it's not easy to figure out which to listen to. And other times you'll get some from folks who will completely trash your wide, or you, use horrible language to make their point, and really are just projecting their own anger and unresolved situations on to you. I got plenty of those too. Obviously, do your best to ignore those hard as it might be.
So, let's look at this from a 50,000 foot level. The key points that folks have been making are as follows:
a) Trying to "nice" your wife back never works. I'll promise x, y or z. I'll shower her with love. I'll tell her why we're so much better together than she would be with OM. I'll use the kids. Does. Not. Work. Full stop. So don't go down that route.
b) Taking decisive action is imperative. Whatever that is, showing strength, setting boundaries, establishing consequences, and follow through are essential. For example, follow Bigger's script. That's an action. Inform your parents and hers. That's an action. Lay down what No Contact means, send an NC text and block OM's number. Actions. It is early, it the sooner you take actions, and you have, the greater likelihood of success. And by that I mean you getting out of infidelity.
c) This is a tough one. Your wife is likely still lying to you. I know that is so hard to hear and comprehend, but it's true. I'm not saying she's an evil person, but a good part of that, if she really does love you and wants to stay married to you, is self preservation. The less you know the greater chance you won't divorce her. Or, she's in love with OM or thinks she is and will still contact him. This is normal for the situation you are in. Doesn't mean your marriage is over, but understand this and prepare yourself. By definition, her cheating is lying. She's been lying to you for months - she didn't all of a sudden become truthful now. So for you, that means you watch and weigh her actions. Her words don't mean too much right now. That breakdown of trust happened. I can tell you it took me a bit to start viewing my wife differently. I'd think, "she wouldn't lie to me" and then it'd hit me what she did and how silly that thought was.
Again in a nutshell:
1) Don't try to nice her back.
2) Take decisive action towards getting out of infidelity.
3) Understand you cannot trust your wife yet and prepare yourself for what that entails.
The rest of the posts you've received are tactics and strategies of steps you can take or warnings of behavior. But the above are key, IMHO.
Separate note: Please, please take care of yourself. Eat, drink plenty of water, exercise. Read the Healing Library (link is in the yellow box in the upper left corner). See your doctor if you are having trouble sleeping (I took Ambien). Find someone you can discuss this with and unload on. We, obviously, are near for you, but having a sibling, parent, or best friend be there for you to support you, would be really helpful. It was for me.
Hang in there Barry. Sending strength.
