Something is very up here. Oh and you know what, I would be posting those pictures of him as your bf, just to see what came out of the woodwork.
But that is just me.
Not something I would advise.

I think the above posters are right. Somethings is off, not so much about the ex, I still talk to a lot of my ex's on fb.
But keeping you a secret. Nah,no,uh uh,nite, Nixie, absolutely not ok.

Good luck, really hope you find the strength to put this him in his place and demand some fair treatment.
