<human>: Give me a shortened version of the text

Hi,
I am 18 year old and my boyfriend is 21, soon to be 22 year old. We've been together for almost 3 years now. 

We are a happy couple. We used to live about 30 minutes apart, but I had to move for my studies and it's now 1h30. Still, he comes and visit almost every weekend. The thing is, I know that we're young, but I was expecting some kind of engagement between us, something real. I told him about getting engaged; he's not sure we're ready. I told him about moving-in; he's definitely not ready to leave his parent's house.
I just feel like there's no evolution, that we're still as we were 3 years ago.
<bot>: In summary: Is it normal for a couple to not get more serious after 3 years? Or should there be something more serious after that period of time?
