Moving to green pastures after pcs

My husband and I recently moved... my job transfer is a four hour drive. My husband would say things like "wow we got this house with us being together in mind and im gonna be alone"... or "who is gonna loon after our dog"...Ever since I started onboarding, my husband and I have been arguing nonstop. He wants me to stay home with our new dog and start a family. While I'd love to do that I just don't feel ready to let go of my vices and those don't mix well with new mom duties and we both come from great backgrounds... I'd like to maintain our standard of living ( NOT SAYING HE CANT DO THAT ALONE BUTTTT REALISTCALLY WHY PUT THAT PRESSURE ON YOURSELF IF WE HAVE NO KIDS) etc. So I may be pregnant or about to start my period (gotta test in 12 day) but regardless, I'm emotional af rightnow...since moving here, my husband and I have ran into a few of his new peers and old college mates (before we started dating)... he did not introduce me to them. MIND YOU I have went to all his military ROTC related events and am known as his WIFE amongst peers and his social followers. ..The first person I brushed off as just us being young and him being caught off guard but then after that it was a girl... I'm not sure if they have history but the way she so deeply let him know that he can come to her for anything and the fact I was standing right there made it so awkward. I grew up as a military brat.. I know military fam initiations vs flirting and this was definitely feeling like a deeper connection...We were out doing stuff so I just went along and played it off but I did mention it again to him and I asked him if he was ashamed of me..(I have been introverting alot from fear of my job and the unknown fed situations).. he said no and he talked about me all the time ( which is true) but idk ... with us indecisively trying to start a family and then this it's making me feel insecure as much as I hate to say that. When we met I wanted to be a sahm and now that he has made it possible I find myself conflicted with insecurities that I never had before and I'm just at a loss of how to move forward.
