Just take your time in this relationship. I have read that anorexia is about maintaining a sense of control.... it must be very scary for you to feel like you're losing that control, or to make yourself vulnerable to another person, which makes sense when it's your first relationship and you haven't been able to trust anyone but yourself.

Trust is something that is earned over time. It should not be automatically given to someone. A person, a partner, needs to show you by their actions that they are worthy of your trust and your heart. A heart is a very precious thing, so giving your heart to the right person, and not the wrong one, is important. And giving your heart to someone fully can be very frightening, as you're recognizing.

But if you know that trust is something that develops over time, and if the person backs up their words with their actions, always, and when you know in your heart that your partner wouldn't dream of hurting you in any way, it's easier to let go of that fear and to fully love. Sometimes relationships don't work out, but the pain of an ending is lessened when there is no harm involved... when someone hasn't done something to hurt the other person. So just know that going forward. Take your time, though. When it's scary, it's best to go slowly.
