I feel jealous

My boyfriend is in the military and lives across country from me. It's been really tough on the both of us but we are managing. recently he told me he and his friends are planning a trip out of state. I'm glad he is going to have fun but I'm jealous that I don't get to travel with him. we've never gone anywhere together and it just sucks that I'm stuck waiting for him to come home. I know I'm sounding petty but none of my friends want to do anything and I'm always working I haven't had a vacation in 3 yrs. I just want to make memories with my bf
