Confession

I've been with my boyfriend for 6 years and he's never mentioned wanting to get married. I've tried to bring up the conversation or hint at how I'm ready for us to get married, but I'm afraid he just has no plans for us to get married, and I don't know what I should do. I don't want to leave him because I love him, but I can't be with someone who doesn't love me enough to want to spend the rest of our lives together.
