LONG DISTANCE RELATIONSHIP.

My boyfriend left to another state 6 months to work with his brother. My birthday is in a couple of days. and since last month he has been telling me that he was going to come to visit. and spend my birthday together. and now he told that he's not coming because he wants to keep on working and save money. i feel that he's being selfish at some point and that he can give himself a break :( it's been 6 months.... how do i respond to this situation. help me please . im mad and sad..
