Help a girl out 🥺

So, my boyfriend and I graduated from high school. I’m going to a local university and he is going to another state for military reserve training... and he won’t have his phone for about 8 weeks and then will stay where he’s at for another couple months or so. We have been together for about a year and 9 months now, and I seriously don’t know what I’m going to do when he’s gone. Any help would be greatly appreciated! 😭
