When will i be proposed to ...

so me and my boyfriend have been together for 2 years and 11 months now. Almost 3 years next month. I feel like it’s been forever. He mentioned he doesn’t want to get married yet because we dont live with each other but he DIDNT mention about proposing to me before we move in and stuff? for my birthday he only took me out to dinner and that’s it. he “said” he was making payments on soemthing last month but i don’t think he still is because he hasn’t mentioned it. So idk if it’s even happening when we hit 3 years or what. He doesn’t really talk about the future with me he just says “we will see”.
