Settlement will be signed soon. Need advice.

[NewB3]

Bought the Gary smalley book. Half way through it. Signed settlement Monday and went to meet new realtor after.
Wife called as soon as I met realtor. Told her I was going to look at houses and would be back later. She said "oh, you have a realtor?" I said yes, so I'll talk to you later....."well, what is the realtors name?" I replied and ended conversation.
Got home later that evening and cooked dinner. Sat down as a family. She said she would help me with any financial information or picking out things, just need to ask. Hmmm, weird?
Tuesday am."There was a big stressor with the paperwork and something I failed to do.....I told WAW that the settlement did not state that. We began to argue on the phone while I was driving to work. She kept saying "I can see how it appears that way, I can understand you're upset...." She promised it was an oversize and that we did not know how to go about this....her attorney overlooked it and would fix. I was pissed and she knew it. We ended conversation. Later that morning I called and got her voicemail. Asked her to call if/when she had time as I know she is very busy.(was giving her an out) she called within the hour.
I apologized for being harsh. I asked her to forgive me for everything as I am just stressed, emotional, and devastated. I am trying to keep everything moving. I told her I appreciate her. Told her I just needed a friend and if she does want this to end up as friends, then we must work on that starting now. Mentioned our C and upcoming appointment.
I purchase a chocolate bar at the grocery the other night. She had a business trip today and left early AM. I had the bar in the kitchen and wrote on it to have a safe trip and be careful. I heard her about this AM from our bed and woke. I called her name tom see if she was gone. She appeared from the bathroom half nude. I laid back down, ignoring what I saw. She then said thank you for the chocolate, I am not going to take it, as I have a snack packed.....I'll just put it away for my return home. Wow....anything in the last few months would have been a simple thanks. Not sure why I get explanations, nudity, and all. As she left, she touched my leg and called my name.....just to say goodbye.
She wore her weeding ring to her therapist Monday, but not worn it since. I still have mine on.
Any advice? This is all new and weird. Being cautious and staying on 180's, still being the handyman as requested ( joking about not charging her for my time) making a few jokes here and there, getting laughs or witted replies and smiles.
