BBM. Not necessarily. I've known plenty of women who never blame their cheating man, but blame the other woman. They tend to stay in unhealthy relationships with the cheater for a long time. And go to extremes to punish and harass the other woman. The cheater will many times encourage and join in on this behavior.
Well I was speaking from personal experience. I was mad, angry, betrayed and my emotions were all over the place. The only person I punished was myself from not being able to eat or sleep. It destroyed my self esteem. I only mention all this because I know how emotions can get out of control. I turned my emotions inward.
