I've been thinking about this a lot today and especially in relation to the gifts. I know if it was me who had just broken up with someone, emotions would still be running high, so they really couldn't win
If they didn't send gifts, I'd be thinking they couldn't have really cared, but if they did, I'd be thinking they were trying to bug me. Emotions still being high, I really wouldn't take any immediate reaction to your gifts, too much to heart
Having said that, I'd perhaps back off now and give her some space to either calm down or have a good think about how nice it was of you to send them - All depends on where she is with it all, but I wouldn't offer any more contact for now.
Look after yourself
