I told her I got her only one christmas present to which she replied that ya I haven't ever given her any good gifts any way , which is not true . I have given her countless thoughtful gifts several times.  
I told her that I can't give her any birthday gifts this year  and then she quickly said she can't either when a few moments ago she was asking what I want for my birthday. 
And then one time I was tired from travel and she showed me her cat pic and I just gave a normal response that ya your cat is cute and she got offended that I didn't respond as excitedly as she wanted me to.  
I  am quite taken aback by this behaviour and don't know what to do.
