Really just need some reassurance..

I'm on vacation. I live in Kentucky along with my boyfriend but I'm down in Florida on vacation for a week. I'm so lonely and I haven't talked to him since I seen him last, which was Thursday. I miss him so bad. I don't mean to be "that girl" but I have nobody else to talk to about it. I've texted him and called him and left a voicemail but I guess he's busy or something. We trust each other so I know he'd definitely not cheat, especially after almost 4 years of being together, being engaged, and soon to be TTC. I just love him so much, and I miss him badly. I'm able to text and call him but it's hard being so far away from him. Any advice on how to keep myself happy and not lonely? Please and thanks!
