I say go and help her because she hasn't seen you much. I think you go put your best foot forward, but possibly have somewhere to be afterwards, depending on the time and situation.
If you don't want a big fight, then don't push anything like the counseling or birthday acknowledgements. If she cared about your needs right now then she would be acting differently, but that's not the case currently so let it be IMO.
So go and put on a happy face and have no expectations.

It is not things that bother us, but the stories we tell ourselves about things.
