military boys

hi! so i've been talking to this guy for a couple weeks now. we've been on several dates and i like him a lot. he leaves for basic training tomorrow and he really hasn't been texting me much within the past day or two. i can't tell if he's trying to distance himself from me because he'll be gone until december or if he's just losing interest. he told me he wanted me to write him while he was there, so i'm going to. but i don't want to seem too clingy because we've only been on a couple dates. i'm trying not to get my hopes up for when he comes back, because he might not even be interested anymore. any advise??? 😢
