Not saying that this definitely didnt happen (it's what I find more likely too), but said user is a big Johnny Depp Fan too, not everything has to be about him.
I'm also not sure if Ioan really dms people. He dmed her once because a relative died. Have my doubts that he would tell anyone besides very close friends if something like this was the case. The way Alice's friends talk about this girl (without saying her name) doesnt sound like this is the clash of two different stories being told but her simply not fully believing Alice's story (like anyone with half a brain). If you read between the lines of some of Alice's posts (
this is from april) she appears to have been asking people close to him in order to find out why he actually left her (or why he fell out of love) and that no one would know, might of course be that they simply just pretend to not know, but I strongly suspect that he keeps this stuff very private.
