No one has a perfect marriage nor a perfect partner. We are just trying to do our best against the imperfection to be perfected into a better relationship being aware that the way to perfection is impossible.Whew...... what a grammar!
Let me say of making our own thoughts here on how to avoid being cheated by your partner. Is this matter difficult to write down?
I think that is the real kicker. Nobody is pefect, but for some reason we are tricked into thinking there must be somebody perfect out there. So we refuse to accept any imperfections in our partners.
First and foremost, to prevent cheating, it is important to commit to resolving issues directly with your partner. For women, especially, the major thing that leads to cheating is when they discuss their problems at home with another man. Men with ill intentions prey on this and those sweet promises of "I will never treat you like that, etc..." are not unbiased advice. The problems need to stay within the couple. For the man, that means genuinely listening and trying hard to never create an environment in which she doesn't feel free to bring up an issue to you.
My fiance has a very hot temper which is very quick and her mouth is quick to say hurtful words sometimes. Me, on the other hand, I am very stoic and calm. It takes a great deal to make me angry. I have learned to let her speak her mind and when she is exhausted from it, then I will engage her in conversation. She almost always sees on her own that she was out of line and will apologize. Then we talk about what the real issue she wanted to fight about. Seems a perfect match because I do not incite her even more and can quickly calm her down. I have found these temper tantrums have become less and less as she has learned how easy it is to talk to me about an issue. The bluntness of a Filipina is sometimes a bit shocking to a westerner. But I prefer it.
I don't have much advice to prevent a man from cheating because I have never cheated and could never imagine myself doing it. So there is nothing to do to prevent it. I think many men cheat on their wifes out of training. For conquest. Men tend to cheat without losing love for their partners. Some men do it to establish dominance over their women by showing them that they are desired and can leave them at any time. It is a power play. There isn't much a woman can do to prevent a man from cheating if he is the type of man to justify it. That is because it is rarely that the woman did anything wrong to cause it.
But some things, like withholding sex and affection as punishment might cause a man to start looking elsewhere. Nagging a man will also drive him away emotionally. And same for not giving him space to be a man.
Maybe the most important thing is to understand what a woman needs from a relationship and what a man needs from a relationship.
A man seeks security through respect and admiration. They get this from the nurturing a woman provides to him.
A woman gets her security through affection and providing for her.
A strong sexual relationship is important. I don't mean just having sex, but the connections involved in it. You can almost always tell when a relationship is falling apart from the lack of sexual connection.
Never gain the habit of withholding love and affection even if you are angry. It is setting a dangerous ultimatum in an effort to get your way. Even when I am fighting with my partner, I always remind her that I love her no matter how angry I am. I don't threaten to leave or threaten the security of the relationship just to win the fight. It may not break you up immediately, but it will eventually.
Security in the relationship is the number one way to prevent cheating, in my opinion.
