could you help me on the correction?

You gave your prime timebest years to someone with whom, now, you now regret to being with together.

And just yesterday you came up from nowhere to telling me that I am the right one who is worth of you want to be with for the rest of your life...

Do you even think it acceptable? Let alone putting you into my case(I want to say: put you into my shoes or something like that). Can you imagine being in my shoes? How would that make you feel?

would you mind correcting this?

I just want it sound like more native and colorful.

if you aren't aware of what I am trying to say. just let me know... thanks a lot

**I can understand your meaning. I tried to change it to use more normal English expressions. **
