Possibly joining Air Force

Hi! I’m just coming here to see if I can get a little insight about joining the Air Force. I currently am married and my husband is in the Navy. We also have a 2 year old daughter. My biggest concern is not being able to be stationed close to my husband, and also how much time I would be away from my baby. I’m looking into something medical, possibly diagnostic imaging. I don’t know very much about the air force so I guess I’m just trying to figure a few things out before committing to going to talk to a recruiter. Also wondering the differences in enlisted, guard, and reserves. I want to look at it from every angle. TIA for any advice and information!
