I don't think it's selfish on your part at all. You want to be with someone that you love and that's pretty typical, especially in the first year of a relationship. I'm looking at this and I see a guy that has his priorities set. He clearly places more value on the traveling time he has over the relationship. That's not to say its wrong or right, but it is just the way he is. Whether or not you want to be with someone that puts your relationship second is something you'll have to assess yourself. But it's clearly how it is and he's not willing to bend on this. On the one hand it's true compromise can come from either end in this but if it were me I would wonder if that will ever change, how long he'll want to pursue his dream over the relationship and whether I'd want to wait. You never know, he may be satisfied after awhile and settle but at this point, he just doesn't sound like someone that wants to be tied down at all.
