distance is a factor. Whether or not a LDR (long distance relationship) is a good idea for you depends on.. well, you, and him, and your expectations. You two need to have a talk about what you both expect will happen to your relationship when he moves, and if you both feel strongly enough about each other to keep the relationship going. just have a very honest talk.. does he want to date girls in Amsterdam? etc.

For me, seeing my boyfriend takes 7 hours in a plane and costs 600 to 900 €, so 3 hours by train would be a miracle for me- I'm not bragging, i'm just saying it depends totally on the persons involved. If you know you can't maintain a relationship at that distance, then just make a clean break and you'll be okay.
keep us posted please
