Wounds of Regret

Listening to the song,
remembering our past.
Wondering if i had done the right thing,
of not taking the initiative to patch things up.
I feel so confused,
don't want to lick the wounds of regret.
Wondering f i had apologise,
would things be back to normal,
back to what we were in the past..?
I don't want to do anything that i would regret,
don't want to feel bad for the rest of my life.

Tell me,
what should i do?
