Sounds like she "really" put her self out there... It's hard to tell how she took your reaction. Men and women see things totally different, so it's possible you thought you were being reserved and she thought you were being something else less favorable?
Another thought is that maybe she gave you the card with the best of intentions but it may have been too soon for her emotionally and it made her feel odd.
I'd act "as if" and see where that goes.
Link to stuff from the spring.. before I gave up...or he moved. Either way.
