For all you know, a different Henry could pop up and say he's married to you. That's how this place works. It's strange, and hurtful, and it takes getting used to. It took a long time for me to get over all my issues with my ex-boyfriend from where I came from, but I did it. Sort of.
Why are you friends with Anne, then? How could you work out your differences and how come you think you can't with me?
