Why can't people remain faithful in relationships?

I believe if you truely love some one you will stay faithful in a relationship because ur feelings for them are so strong that u only have eyes for them. However I also feel that people may be tempted by the grass is greener syndrome.. they may think they would be better with someone else.. when people are like this they do not truely love the other person because they otherwise would not want to hurt the person they are with. I feel there may be a "dog" or "Devil" in all of us but some people know how to say no and know what they want and that what ever they are feeling if they are tempted will not last. Once a cheater forever the person will remain so... this is the most true thing i have ever heard. It is a shame so many people cheat because a relationship should be special and it should not be ruined by this behaviour.

In my opinion, the couple should trust each other. If they can see their future as the husband and wife , I think they will be faith to each other. But if the couple is still in young age,or still in their "youth" mind, there is the possibilities for them to search another option for love.

People who loose faith in the ONE MAN ONE WOMAN concept, people who cannot conrol their minds, people who have no respect for others feelings, people who are easily corrupted by lust and desires get into these kinds of problems. This social evil continues to be there until a person develops courage and conviction to stand up for principles universally acceptable.

I wonder the same thing. There is no right or wrong answers to it. I always compare others people's relationships with my own because I think I have a very good relationship with my hubby. Mental weakness is in everyone I think. To able to control your weakness might help to have a better relationship.

How to stay faithful? Maroon yourself on a desert island with your partner.

I have never actually cheated on someone, I have on the other hand been cheated on and I have always wondered the same thing, why can't people be faithful. For me being faithful is easy. I know how it feels to be cheated on and I would never want to hurt my husband in that way. I think if you really love someone you can stay faithful. It is all in your mind you have to say to your self you just aren't going to be unfaithful.

I agree to this its a sign of mental weakness. I have the same experience if i think my past in one angle. She is unfaithful to me she jus cheated me which make me to suffer alot, it took 2 years to get recovered from the frustration. Still they are existing in some places, they don't know the true meaning of releationship, they won't involve deeply, they will get changed according to the situation. i dont know how they can able to forget all the past within a second and tries to cheat some other...... They are cruel minded people who doesn't know the value of true releationship. May be i think those are unmatured minds.
