He’s so different

My husband is in the military. Last year he deployed(non combat) and while all my friend’s husband were calling, face timing, whatever, my husband never wanted to talk to me. I’d literally beg him to call me. He would ignore my calls, tell me to stop calling, tell me we have nothing to talk about. He came back, apologized, said it wouldn’t happen again. Well of course here we are again 😒 he’s away for a few months and he already refuses to call. Meanwhile the guys around him are calling their wives 😔 I just don’t understand. I don’t ask him for anything but a phone call on the weekends when he can. But when he can, he refuses. His first deployment, before we were married, he never did this. I didn’t have to ask him to call, he called because he wanted to. He’s deploying again soon and I feel like he’s going to do it again, even though he promises he won’t. It hurts that he has the opportunity to call but just doesn’t want to. Just call and say goodnight, ask me about my day, literally anything.
