So you're saying that allowing her to get close to you and building up the hope of starting a new life with you back in our world -- one fractured and recovering from a war, where she'll have far more responsibilities and burdens put on her -- is acceptable to you, but expressing a desire to marry her when you may very well be trapped here indefinitely isn't?

If you're going to be selfish, at least be consistent.
