I wouldn't say she's "playing you" as much as she's realized you two don't have as much chemistry in person as she probably imagined. These relationships that begin digitally can be very deceiving. A woman's imagination can have her falling in love with a certain version of you that isn't reality.
I'm curious what this detail is. I'm also curious what this lie of his was about. You don't have to say. But it seems to me he was being deceitful and manipulative from the start. I don't think he's as relationship minded as he wants you to think he is.
