Is he ready?

My name is Tiara and I’m 20 and my boyfriend is 23....

So my boyfriend and I have been together for 4 years now on and off, and we’ve talked about marriage before, but we both agreed that we are not perfect and we are both working on each other but we want to marry each other. He talks about it but it hasn’t happened and now I’m starting to think he only talks about it to satisfy my thought of it. Idk what to think or anything, I want to marry him he’s so great 😭
