I feel lied to

So shes been very avoidant for a while now. With random bouts of warmth. 2 days ago she came back started being sweet calling me hun and love again complementing me and not ghosting. Sending me explicit pictures and yesterday to. We'll today on valentines shes been basically ghost. Which really hurts becuase I thought we were getting back to the old us. Amd im just worried she sid that so I wouldn't question what she was doing today.
