Military wives

Ok so i have been doing very well with the idea of my fiance going to basic training and going into a new life style. However his MOS options bother me and i have no idea how to cope. He loves special forces, infantry, he thought of making a switch so he could be a seal, ect. So now i am just a mess because i know those require a lot more deployments, late nights, unknown places, being by myself, and more, so now i am not handling it so well. Some words of encouragement or advice would be so much appreciated because i just have no idea what to do with myself. And on top of that we may be expecting (i know great timing right? Lol) so i am not sure how i am going to cooe with being by myself at this time either. Being an Army brat didn't even begin to prepare me to live the life of a military wife all it means is i know the language and some expectations a little better going in 😔😩
