Personally I think it's incredibly rude not to thank someone - no matter what stress you're under. Even if she had a bad time over Christmas (and we're only supposing that here) that's just not an excuse. She could still always say "thank you" and then go on to say that over Christmas someone dumped her or someone died. Lots of people thank others after losing a partner, parent etc.
I was always brought up to phone or write after someone had given me a gift and I'm glad of this. The late Princess of Wales also did this. Many people remember receiving a hand written note from her after some sort of gift, invitation - no matter how small.
At the end of the day there's nothing more true than the old saying "Manners maketh a man" and a woman also !!
Personally I wouldn't bother asking her if she liked them - it's up to her not you to do the chasing and finding out. You've already done your bit by choosing and thoughtfully buying the gift. You could ask if she had a nice Christmas/New year though.
Try not to let it bother you - it's not worth it. At the end of the day she's done herself no favors.
