Tinder and Basic Training (long post)

Alright, I don’t post on here like ever, but I need advise. I met this guy on tinder and we’ve been talking for like 2 weeks now. (I know, not long) When we first started talking he was in my home town for a couple days before he was flown out to FT Jackson, SC for basic training for the Army. I didn’t take the opportunity to go meet up with him before he left and I regret that decision because now I miss him a lot, but it’s weird to miss him because I haven’t actually met him. Over the two weeks that we did get to talk, we kind of developed feelings for each other, which doesn’t help the situation. I write him often even though I know I won’t hear anything back for a while, and I told him that because I want to get to know him better I’m going to wait until he’s done and not talk to any other guys in that kind of way because I want to give him a fair chance. I’m still going to do that, and don’t have a want/need to talk to other people, but it’s hard to know what to feel when I know I’m into him, but don’t actually know him. I guess I just need reassurance because I’m also scared about the fact of what if he gets stationed somewhere else and I never get the chance to know him. ☹️ He’s a really great guy from what I know and it’s even better because we have a lot of the same interests and beliefs and are both looking for more than just a hook up, but 10 weeks feels like an eternity, and even then he’s not home right away.
