Any advice for a first time girlfriend who’s SO is going on deployment?

My boyfriend is leaving tomorrow for a month to do tests and missions on a ship before an 8 month long deployment. We’re long distance as it is, but we rely heavily on FaceTime and text messages for communication. I’ve been struggling lately and he made a comment today that a friend of his said it was easier to these things when single, so now me being an over thinker i feel like he’s hinting at something.

I just want to be able to love and support him through this without my emotions showing through too strongly. I don’t want him worrying about me when he’s away. Any advice?
