First i cant put me in the situation.... i think i will never be in that kind of situation.
but, if in case then, itz time to forget if itz the first time. next time if this happens quietly take ur kids(if u have) leave him/her and settle alone r if u find a person, someone who really loves. thatz how i will decide. Running behind is not going to give u either a solution r peace of mind. accept the reality.
