Woah,go slow,woman!All the options laid down suck lollies and eggs,much to your rue,sorry.As it is,you should know how dangerous the effects of generalising are,beware.You cannot just blame unfaithfulness solely on men(have some mercy on the poor chaps)and the same way,it cannot be blamed entirely on women.But I have to say this(not generalising)MOST men are found guilty of it and when compared to women,have an upperhand in this tale,as it's in their nature or maybe their extra-maritial affairs are deliberately made to go public,whichever way it is,there's no running away from this fact.Having said that,TIT for TAT,in case of marriages doesn't work,I can't believe option no. 4 came from a married,sane woman!'Blame Games' ?nah,worst of the worst.Sit down with the unfaithful lad or babe,and discuss it over,communication and understanding helps alot.Unfaithfulness is very agonising,especially when people do it just 'out of habit',now..how preposterous is that?
