help!!!

Me and my bf are growing apart sort of but I feel like I'm the only one that notices!
We used to talk every minute of the day on the phone or through text. We always facetimed each other at night before we went to sleep and woke up on ft the next morning, we were very close!
Now he doesn't text me goodmorning, he doesn't text me when he's at work, he doesn't phone me on his way home and we don't really speak when he is home because of his training.
I feel like I'm not even in a relationship at the moment but I feel like he isn't bothered by it :( help me out ladies 💓☹️
