What If...?

Ok guyz imagine this...
Your ex is back to you again..he/she is begging you to return to each other and be like before...and he/she apologizes SO many timez abt what happened and says there was some really hard circumstances..would you trust this person??? what would you do AND why would you do that????

give him a chance and if he is lying kick him in the balls to teach him a lesson

OK guyz :
I'd say absolutely what used to be between us will never to be the same...otherwise things will definetly change 100%
becuz even if I gave him another chance..in my heart there will always lie this pain and will never to be healed
so what do you say??
am I right??
