My boyfriend and I have been together for almost two years and we've been long distance since we met. We're finally moving in together, but I can't get him to book the flight. He chose the 26th of Dec and he said he'd book it this past weekend, but didn't because he now wants to go to his niece's birthday on the 29th and now fly out the 30th. That'd be fine, except I'm transferring schools (in my own city) and my orientation is on the 2nd of Jan. I want to have moved by then to try and lower the stress of starting at a new school. I don't want to be preparing for school while unpacking boxes. He's moving states for me so I want to try and be understanding and let him stay for his nieces birthday and be with his family- I agreed that he could spend christmas with his family- but three days or less is not enough time to move. I just don't know how to say no without feeling evil and selfish. I just need advice on how to explain it to him, or if I should let him go to the birthday party or not.
