Then she suggested that we get our winter clothes on and go to the beach to take some "fun photos" and "be silly in the snow". I said sound like fun and I'll bring my boots.
I don't expect to be anything but a good friend to her right now and she's making it pretty easy!
That sounds great! Remember to just take it slow, but be playful and exciting for her. She's obviously missing you a lot and is really needing you around. You'll probably find it really weird - I've noticed that my friendship with my W is much stronger than it was before the bomb. It's not perfect by any means, but we do so much more together than we used to.
