It's a toxic relationship. You two aren't good for eachother but god the relationship is too good to give up. It's a vicious cycle of cheating, forgiveness, makeup sex and back again.

This time it's his turn to beg for you to stay. You found him with another girl and were finally ready to leave him but now you find him on his knees clinging onto your legs.

"Don't leave. Say I'm the only one you need. Say I'm the only secret you keep. Don't break me down."
