If you had feelings for another man, you would end your marriage first... It sounds to me that You were already having an affair of the heart. Shouldn't an affair of the heart be consider as cheating?

How many times have you listened to people who divorced their partner that they never intended for it to happen? That they had a perfect marriage and the other person was just another friend from work?

I actually believed they never wanted to cheat their spouse but sometimes things happened. All you need is a chance to be exposed to that element that will make you fall for it.
