He hasn't asked me to marry him 😓

Catalina
Me & my partner have been together for 8 years. We have two children, house, cars, everything Together. For some reason he hasn't ask me to marry him! I believe we have regular relationship issues like any other couple but I'm starting to feel confused & some what sad about this. 
Anyone deal with this & what did you do about it? 
Note: someone told me to ask him first. I do t like the idea of that 😑Â
