New to military life

So my boyfriend enlisted straight out of high school and is in BCT right now. We have a dog together and are planning on getting married in April during his AIT. It hasn't been too hard yet because I write him every day and keep telling myself it'll be okay he's coming back soon some days are harder than others. But any tips or advice on anything related to being a military wife or anything with the military life in general would help lots because im completely clueless😩
