Not saying it was necessarily fake (although it may have been) but that that kind of rapid escalation in grown adults is always a little suspect. On your side, you had a big hole to fill from your divorce and may have overlooked red flags. From her side, she might have some big issues you're not aware of.
Just saying most experienced adults would take it a little slower, and the fact that she jumped in with you like that is a little suspect on its face.
(BTW, when my ex and I fell for each other in our 20's, it was similarly intense - mostly from him - for the first few months. Then his behavior began to not match his words. Many years later I know he's a narcissist, one of the dark triads that love bomb to reel people in in the beginning.)
