No I don't mind, and no its not.so, if you don't mind me asking, is this your brother's situation?
He tends to believe that once people are together and "love" each other that they should do whatever it takes to fix/make a marriage/relationship work. He feels that if they love each other a little thing like infidelity can be gotten over.
I think it can to, but people are to selfish and petty sometimes(both partys) to realize that doing things like that can hurt someone real bad emotionally and when they keep doing it, sooner or later it is going to make things unrepairable. It no wonder the divorce rate is 1 divorce out of 2 marriages. It is getting to the point where a monogamous relationship is going to be a thing of the past. But with drugs like Zoloft and Prozac for depression, it is no wonder they are some of the most prescribed drugs in America.
