Boyfriend is leaving for a year over seas and I need advice..

Very long story somewhat short, me and my boyfriend are doing long distance(across the country from each other). We see each other every couple months and even that is hard. Now he has orders to be stationed over seas for a year which means I will see him in person once in that year.

I’ve already cried about it and come to terms. I only have 4 years until my contract is up and then I plan to go live with him until (hopefully) one day we get married. All my friends are telling us to just get married now so they send me there with him when it’s my turn to PSC but we both have been married before and those marriages were both rushed so we are not rushing and want to do this right.

My issue is, what if I forget how amazing our relationship is and how perfect we are together while he’s gone? When we are together I am just reminded more and more how much I want to spend forever with him and I’m scared I will loose that feeling when he’s gone. I feel so shitty for even thinking like this, but it’s happened to me before with an ex, although that relationship was not even close to as strong as the one I am in now.

I need encouragement and advice❤️ we plan to FaceTime as often as we can. I will send lots of care packages to him and he will send me fun stuff and snacks from the country he is going to.
