Feeling lost

[srt]

my wife has recently been complimenting me (ie nice t-shirt, I like what you've done to car/house)

I've been acknowledging this by saying thankyou, and not really doing much else.
If this the DB way of dealing with this - I am unsure as to whether I'm being tested or anything else like she is trying to be nice - I guess it show she is noticing changes, and I'm trying not to "pursue" by echoing back.
Any thoughts?
