Yes despite our best efforts sometimes its hard to separate the actor from the character when we have really strong feelings about that character
And thats why I think Jamie is getting a lot of hate from Mortal Instruments fans right now because everyone is just really really attached to the character of Jace.
But Jamie and Bonnie do look happy together and thats really all that matters so I wish them well
I just can't believe they're engaged at such a young age!
