Most Helpful Guy
If he doesn't want to get married, you can't force him to. It can wait. Relationships are supposed to be about giving and taking, so you have to be able to take this.
Just be honest and tell him your true feeligngs. Let him know that you are hurt that he went to the recruiter behind your back. Let him know that you don't want him to lose his life in the military, and if he joined, you would miss him a lot. You have to let him know what you are really thinking. Use emotion to show him that you really mean it.
