Will I really be Mrs....? Or is this just to keep me around?

We are both in our mid 20's. Together for quite some time.

Back when he was on vacation, he sent me a text asking when I would want to get hitched.

I said a year from when he proposes.

He then sent back - You're perfect! That's why I'm going to make you Mrs. (his name) one day.

That was the last time marriage was brought up from him.

When he talks about me to his friends, he always says he has no complaints about me. He has told some important people in his life that I'm 'the one', and I'm perfect for him. I believe him 100% when he says this. if he had a problem, he would tell me in a heartbeat.

Literally, we never fight. We have nothing to fight about.

Today, he text me saying I love you. I said "I love you too" and he asked if I was sure.

I said of course, why do you doubt my love for you? He said he doesn't, just likes the reassurance.

To flip the tables on him (he asks if I'm sure at least once a month)

I asked if he still loved me - he said yes.

I asked if he still thinks if he'll marry me someday... he said of course.

So, my question is, do you think he will really marry me?

I am ready, and we live together. I feel like that is our next step.

I don't know if I could wait another 3 years. LOL.
