Army Girlfriend/Wives ❤️

My boyfriend enlisted in the army and has been gone for about 2 months now out of his 5. It's actually been really kind of hard not being able to see him or talk to him everyday like usual. Any words of advice? Any stories of your own? 
Some people say "absence makes the heart grow fonder," Is that really true?🤔 
Did notice any changes in your SO? 
It kind of scares me a little. We've been together for 2 years now and it's really different being away from each other for a long period of time like this.
