Today my boyfriend told me that he plans to join the military sometime soon. This is completely out of the blue because he has never once mentioned any interest in the military in the two and a half years that I've known him. This really shook me hard because I've seen many relationships fall apart because of the separation and commitment to the millitary. When he told me this I just didn't really react... I know I should be supportive of this decision, because it's better than not having a life plan at all, but I also don't want to see us fall apart. What am I supposed to do? Is it selfish of me to tell him to stay?
