Infidelity

I think this is always wrong- if you are with someone, then you shouldn't want to go off with anyone else behind their back! If you do, fair enough but finish with them first as you're obviously wasting their time being in a relationship with them?! And if you're doing it to get back at them because they did it to you then why didn't you just dump them in the first place as soon as they had done it?!

I might be wrong here but I think its the person in the relationship who cheats that is more to blame than the 'other woman/man' bacause they are the ones who have made a commitment to their partner and should not go against this!
