What to do...

Helpmeeeee. I'm in the military, but still just a specialist. I have a crush on my sergeant (which is no bueno) and I'm just really not sure what to do. I have very little romantic experience, so even if I could get past the fact that he's a sergeant, it would be difficult to steel myself enough to tell him. Not to mention he's divorced and has a daughter. I've liked him for a very long time now, so please do not underestimate my feelings. Advice would be appreciated
