A while back, I've been with this chic for 2-3 years and the relationship is awesome from all level.
After graduating from uni, I decided to go overseas to work etc and we broke up over the phone after 6 months and neven speak again.

1 year after we broke up, she visited my town and asked my mates about my contact details. And we met up, although she knew that I still have a strong feeling.. She feels annoyed as I haven't answered "the ultimate one question that she has been wanting to know" (it's about my past)

And now, she lives very close to where I'm. We often bounch to each other. However, we look like a total stranger or at least, I can see some weird/grumpy face on her.

Question: is it wise for me to invite her out for a cup of coffee and clear out all the questions she has asked but never being answered?
My objective: I don't intend to go back to a relationship with her (as I'm happy where Im now). But I just want to be friend with all people or at least no stranger with the people that I've met/known before.

Thanks for your advise.
Cheers!
