calling out the military wife's

So my husband is being deployed next year.. and he is in the airforce and for what he is going to be doing for the 8 months is not why I'm worried.. I'm worried He might cheat or something.. I love him to death but I always have had a feeling of emptiness.. like something was missing from our relationship.. is having a baby gonna fill that hole..? I don't think I or he would actually cheat but I know I would want someone to be there to stand next to me and hug me and tell me everything is fine but idk if I could get that from family and friends or just a guy I know from where ever.. any other girls in relationships dealing with military how do u feel about this?
