SEALS Spouse??

My fiance and I are getting Married in August and sometime right before the New Year, he's joining the Navy and training to become a Seal. Hes been studying and working out even now everyday because it is all he's ever wanted to do in his life. This made me want to start researching things and I found out that the divorce rate for Seals is 90%. I've been so upset and just need some encouraging words. It feels like him joining the seals is practically damning our marriage before it even starts. I support him and I know that he can do it. I'm also a bit selfish though and don't want our relationship to suffer because of this. 😢
