<human>: Can you condense the text into a few key points?

We've been together for 4 months, and we're perfect. My longest relationship prior to this lasted for 6 years, never married, and I've never felt anything like this before.

I kind of live at her place for the last 3 months. And, though she's not pregnant, we already discussed the possible outcome of unexpected pregnancy, both being totally ok with that. And we both talked about it and imagine ourselves as being married in the future. And, I'm not a youngster anymore, so I know it's not a flick.

It's not typical of me to seek such advice, but here I am doing it.

Thus the questions -- is it too early to propose after 4 months of being together? I know she would say 'yes'. I don't expect to marry her right away though, I imagine we'd do it after a year or later. Is it ok to be engaged for longer periods of time?
