First Deployment advice

Hi ladies, my boyfriend is currently deployed and it's been super tough. He's been away for months at a time before whilst we've been together, but he was still in the same province/country as me.

We're still able to talk on Facebook occasionally whenever our time zones match up but I can't help but feel like I'm annoying him since I get so overly excited when he finally messages... I'm super talkative and love texting but he's not really like that if that makes sense? Near the beginning of deployment he was very talkative, told me how much he missed and loved me but not really anymore. I know he's super busy but I get needier and needier as the days go by.

I need some tips or advice on how to make this easier.
