Signs of a cheating military boyfriend, what should I watch for?

Anonymous
The title pretty much says it. He JUST joined the Air force. I do really trust him, and from everything I have seen and heard from friends and family, he is a great guy. I've been cheated on and hurt so many times by Army guys. My man is Air Force, not Army. I'm just so paranoid that he may be tempted while in tech school. What should I watch out for? Are there any signs? It's hard to catch the normal signs when it's a long distance relationship, and military life is very hard for both the guy and the girl.

OK yes I didn't trust him bec I'm insecure, but now we are fine, he has done NOTHING to make me suspicious. he's a great guy and now a great husband.
