DARK - how do you do it right? I need help BADLY

[DTM]

Well dinner was a success - all smiles and light conversation, no mention of R talk whatsoever. While at home we both pretty much stayed busy with our own thing, spending time with the kids, etc until bedtime. After tucking in the two kids I said goodnight to the W from a distance & then we passed in the hall...I noticed that she began to lean into giving me a hug (which I would've loved) but I didn't say or do anything..just smiled and told her to have a great night. I don't know what she may have thought about it, good or bad.
She probably stayed up until the wee hours of the morning doing whatever she does on her phone and the internet...and that's that. I believe that these past 4 days have gone very well for me...a lot of patience, no push to talk about anything, minimal texts, etc. I would bet she likes what she is seeing right now but know I have to keep it going a LOT longer. Sometimes we hang onto the smallest things....my 8 year old daughter told me earlier in the day (when she came home) that she and her brother missed me and then said "mom misses you too"...of course that could've just been my W being nice to the kids but it was good to hear and wish that it meant something.

Carrying on...I appreciate the support.

BTW - I broke off the interaction I had began the other day with a woman I met.(total of a few hours on the phone, some texts and a 4 hr "date".) It was too much guilt in my heart to go outside the marriage, even if it's a mess and my W says she doesn't care and "expects me too"...I think she does care and I appreciate the responses here to get me thinking straight again.
