Anyone want to take a stab at helping me interpret my W?

Ok.. I know, if I can't make sense of her no one else will... and really this post is just me venting a bit. I'm not truly seeking interpretation because ultimately it doesn't matter. She is what she is and will do what she does. But here is what has me... not upset, not angry... frustrated is maybe the right word.

Some quick background... My W and I inventoried most everything in the house and came to an agreement of the value of those items. Those things that are staying with the house I agreed I would "pay" her 50% of the agreed upon value. Example: five year old couch is $250 so she gets $125. I was pretty liberal with this approach and didn't demand half the value of things she was taking. Why? Eh... it might be $700 or $800 I'd get and not really worth it to me right now. Ok, so, since I don't have the actual cash I agreed to pay for things on my lines of credit which I will pay off in the coming months. Granted we're still married so these are her lines too, but that's a risk she has to take to make this work. Ok, with me so far? So I've been purchasing things she's identified. Why? because I didn't really want to give her my credit passwords or physical cards. I don't think she'd just run up a bill, but I'm not a complete sucker either. And these are lines in my name only... they are only joint because we are in a community property state. But if you run credit reports they only show up on my report.

Ok... so today I pick up a few things she identified. I emailed her to tell her it was done and to tell her some things had arrived. We agreed I'd let her know these things. Here is the email I get back:

"Wow…thanks! ... I appreciate the help immensely and can’t tell you how thankful I am that you are such a wonderful person! So again, thank you."

Really? I haven't done anything with her response. I don't know if I should ignore it, acknowledge it and move on or what. I'm such a wonderful person... aw shucks, thanks. Part of me is glad she said that and part of me really doesn't give much care. And another, darker, part of me says to file this in the "don't listen to most of what they say" because she's just trying to manipulate me by being nice. I hate seeing shadows where shadows may not exist.
