The fact that you lured him with a fake profile is weird indeed. You got issues darling. But he did play behind your back. Confess you are the one who did flirt with him and then dump him. And never to that again.

Talk to him, whether it is face to face or even through text if you don't feel you want to face him down now. You have your not so sweet proof in the pudding that he is hooking and cooking with other girls online and you are not the only one he spends his time with.
He is a free bird who never made anything Official and Actions speak louder than words. He should have even told you both to delete this online fling thing then.
Perhaps he wanted to see First how it might work out but in the meantime, he is still out there in the call of the wild.
Talk it out and see if a compromise can be made. However, being 'Online' one never really knows for sure unless he actually tells you you are the One and even then, life and love is still a gamble.
Good luck. xx
