ADVICE NEEDED!!!

So my boyfriend has finally decided to go into the Air Force.. he’s been thinking about joining for a while and he sent me this tonight.. I guess the real reason I need advice is because I love this boy with my whole heart but long distance has never been my thing and he knows that. I definitely wanna try and make it work and I’m trying to be as supportive as I can but I’d like to know if anyone has any tips on how to make things easier? Thank you in advance 💕💕
