Hello everyone!

Me and my boyfriend have been going out for 4 months, and he is moving to another state. I won't see him for a year(so yes he is coming back). I really love him a lot! But I don't know what to get him 4 his goodbye present which makes me feel like I'm a bad girlfriend if I don't get him a good present. I was thinking of something romantic but I still can't find anything that expressed my love for him!!
