<human>: Can you provide a brief rundown of the text in within 3 sentences?

My(16f) boyfriend(18m) of two years left for boot camp two days ago. I had no idea how I would get to his graduation but a good friend of mine offered to pay. I know he will. He flew me down to see my dad for the first time this past summer. I just need my dad's permission now. My problem is that at these graduations there is usually a limit of guests. (3) His mother, father, and then either me or his brother. His brother(20ishM) is in the Navy as well. He wants to go to his graduation. There's one spot. Who should get it? Obviously I want to go, but I understand that they're brothers and family is more important than our relationship. But, it is his graduation...
<bot>: My boyfriend brother wants to go to his basic training graduation, as do I, but there is only one spot available.
