Ultimately no, he doesn't need Alex. But its possible he dislikes me enough now that he's happy to keep her around to get to those around her. Tom already despised him for being what he is, now he has more reason.
I don't know. I have no idea what I need to do to fix any of this, but ultimately, she made her choice and I made mine and much as I still care I won't change my mind until she realises just why I was so angry. But its not something anyone can help with exactly, besides you have plans, you go, enjoy your time with Elijah.
