Needing advice or encouragement!

I’ve been dating my boyfriend for almost 4 years now and I’m so ready to marry him but he’s not ready at all. I bring it up so often that I actually feel kinda bad but otherwise he’ll never propose for another 5 years. It might seem dumb but I think about it every day and it makes me really freakin sad.

He lives half hour away from me and we don’t see eachother that often and when we do it’s just for a couple hours.

I know he won’t marry me for another couple years, anyone have any tips for me to get through this and being content while I wait?
