Long Distance Relationship

So I'm in a long distance relationship and haven't seen my man since early July. What are some ways to spice it up a little? I feel like we are in a rut and that he's getting a little frustrated. A little back story is that he was stationed in my hometown and medically discharged 1 month after we started dating. I had been talking to him since March and he helped me through a bad breakup + the rebound after that. He's literally my favorite person and so understanding of all my quirks so I want him to be as happy as possible.
