Welcome to our forum.
I hope this first meet-up with your wife and this other guy goes fine. I'm sure it will. Keep us posted on how things are going, and let us know if we can help.
Things are often a lot scarier in practice than they are in theory. You just need some time to get used to the "new normal." I'm sure your wife will come back to you, and have lots of stories to tell.
Keep checking things out on our site, and see if you have any questions. I'm glad you could join us.
Love means never having to say, "Put down that meat cleaver!"
