need advice!

AlI • Married ☺️

my boyfriend is going into the air force and he is currently in basketball for his senior year and that takes up all out time we are lucky of we get a 2 hour call I get to see him once a week and now his mom keeps doing stuff with him and not letting him visit me on Christmas break yet he leaves June or July I'm so upset he don't understand. 😔 it's upsetting I want to visit as much as I can before he leaves. his mom says that in three years I'll be living with him so she wants to spend time with him yeah three years why can't she be fair he isn't a toy on a play ground she's so freaking childish... do I have a right to be upset and how can I detract myself when she won't let him talk to me?
