Is he ever gonna propose?

Okay I just want some insight on a situation. I’ve been with my boyfriend for 6 years. I’m 20 and he’s 23. We just got an apartment together 6 months ago. We don’t have any children. I love him so very very much and I know that he loves me and adores me. We have talked about getting married and have both agreed that is something that we want. Although I have been getting a little impatient. I would marry him tomorrow. I have dropped MANY hints and I probably talk about it a little more than I should. Ik some people say if he doesn’t marry you after so long he probably isn’t going to. We have been together since we were basically kids. And we’re still pretty young. What is your opinion?
