We met {accidentally, by chance---we bumped into each other} Nos hemos encontrado..... Nos encontramos..... -------------- We met {in the board room --- there was a scheduled meeting and we met} Nos hemos reunido... Nos reunimos...
A veces me arrepiento nunca haberte conocido (I think this means 'Sometimes I regret NEVER having met you'; and the question saying '....EVER....', you would use the same sentence minus 'nunca', since the meaning is 'Sometimes I regret having met you', the 'ever' merely a reinforcer).
