Frankly I wouldn't give him anything at all. You've only been with him for 4 months and now he's leaving the state for (at least) a year. He obviously doesn't have a strong commitment to you. I don't mean that in a negative sort of way but if you impute more to this "relationship" than there is, you're going to end up disappointed and hurt. Don't lead yourself on, which is what I think you're doing.
