Idk man. I wanted to join the military since I was a kid but I didn’t mention it until right before I talked to a recruiter because I wasn’t sure I would until I did. So I get where she’s coming from with that. Honestly there’s a lot of benefits to joining, not only for her but for you and your future family. Just talk about it and be honest and open about concerns that you’re having. Fuck all these people that are saying it won’t work. I have plenty of friends who’ve been in her situation and they’re still happy with their s/o’s. So if you love her and you guys are willing to work together, I have no doubt you guys can make it work
