I need advice

Maybe I’m being crazy or maybe I just really don’t understand how much time the army takes up. So I’ve known this guy since he was a senior and I was a freshman we talked that whole summer then stopped and then we talked again about a year later and stopped now another half a year later where talking again. Now all the times before that we where just friends but this time he’s obviously flirting but he’s always leaving me on read or not texting me back he says he’s working but my past relationship have made me so self conscious that I can’t control how I feel. He’s FaceTiming me when he gets the chance, complementing me, and texting me. These past two days though he haven’t texted me very often maybe a few texts here and there but nothing huge but he FaceTimed me tonight before he went to the movies. During the conversation he insinuated that this week was really hard. I know I sound like a crazy bitch we’re not even together and I sound like this and I hate it but I just need to hear from people who have husbands or boyfriends in the army if this is normal or if I’m just being played. Again i swear I’m not a crazy bitch but I’ve been played and used so many times it’s hard to trust anyone again. Thank you for reading all the way through if you have.
