Insecurity?

Why don’t u trust your husband, is it insecurity or you know that he’ll cheat on you? This is the topic from Class 95 FM. FD had left this question for the listeners to think about. Here’s how I felt.
Too much expectation would make one feels insecure. The expectation now is to be a superwoman, on one hand, she has to be the mummy to both him and the kids and of cos to be a wife to be there whenever he needs her both mentally and physically, she also has to be his support pillar, listener, anger venting machine and lots more. She even has to look good and maintain her figure even though his has grown sideways. From day one, women had been known as the weaker sex no matter how much we try to prove ourselves, which is so sad!
As for the second part of the question, even if the husband were to tell a lie about anything under the sun I would say that he already had broken the trust especially from someone so dear to him. It is always hard for a woman to let go and pretend that nothing had happened.
No matter what kind of cheat, be it mentally or physically, all these can be classified as one being unfaithful to the other. What happened to those marriage vows that were taken, are they all forgotten or just gone with the wind! Well, like I also say, if someone wants to cheat on you, there are always thousands and one reasons for his action. So anyone can suggest any preventive measures to take on this issue??
