OP, try this thing called "communication." Of course, if you tell him that you expected him to spell out "Will you marry me?" in the sand, then there is the off-chance that he looks at you incredulously and thinks you are a psycho mega-bitch. But you should definitely find a way to tell him. Otherwise, nothing will happen. Getting married is clearly a priority of yours; chances are he doesn't see it that way.

Have you talked to him about your desire to be married yet? Maybe he's the sort who never wants to get married. Let him know it's on your mind and if he doesn't feel the same, then you have a very difficult decision to make. At least you'll know where you stand.

have you been together since you were 9? thus making it still somewhat age appropriate for him to act that immature?

Ne-ga-tive.

It really sounds like you two need to have a serious discussion. Looks like you're ready to marry, but is he? I really suggest seeing where you each respectively stand in the relationship now and if you both see it heading for marriage(ensuring you both want that). Best of luck to you both.

9 years waiting for a wiener? OP, rethink your life please instead of just saying f..ck it!
