Thanks so much for the words of encouragement - it does help knowing I'm not the only one going thru this. It's funny - while going through the whole deal, my sitch played out almost exactly like the DB books said it would. I found real comfort in this - I read and re-read and re-read. They were my security blanket. But now I feel like I'm "on my own" and don't know what to expect.
My biggest issue is insecurity. He came back to me, ended it w/the OW, so in some ways I should feel GREAT! And while overall I do feel VERY VERY happy, I also feel very scared and insecure. Almost like I'm sure something bad will happen... This is a tough part of DB'ing - I was the strong/determined one and I got what I wanted (and still very much want). But now I just want to be the scared little girl and be taken care of and reassured.
We have talked a little - he knows some of how I'm feeling and is trying to be attentive/reassuring. I honestly don't think there's anything he could really do to make me feel totally secure. Like people have said here, I guess it just takes time. And I think I just need to think through it a bit more and to take a deep breath and find just a little more strength from myself and not look to him as my only source.
