Post breakup conversation

I, M39, recently broke up with my F partner. Our relationship lasted only 4 months, but we have a solid friendship of almost 3 years built up. We had previously tried to date once before, within 6 months after meeting, and that didn’t work. We kept in contact, both personally and within our friend group, and let the friendship continue to develop naturally.

It has been almost 2 years since we went out the first time, so we tried again, this time more seriously. And again, I broke it off out of my own fears. We both love each other for who we are and want to keep it friendly.

I suggested to meet outside at a park and have our talk. My partner sounded a little bothered. Would anyone had a better suggestion?
