Certainly, you never wish to have a deceitful couple. Dishonesty is something that is able to break your relationship. When you find that he lies to you, your trust in him will be broken and it is hard for you to trust him again.
In fact, we should always be honest to our partner. Once you lie, it can be your bad habit. When you start to lie to him, there is a big chance for you to lie to him again and again to cover your first lie. It can cause a stress on yourself since you hide something while you are thinking many reasons to support your lie.
Robert R. Butterworth, a psychologist from Los Angeles, said that you may lie to other people, but you should not lie to your beloved partner. You should always try to give the truth for him, no matter what the problem you face. Sometimes honesty hurts you, but it is better than deceitfulness. You would not get intimate sense in a relationship with deceitfulness.
It is hard to forgive and forget him when he lies to you, but you can still try to forgive him when you know his reason why he lies to you. Listen to his reason and try to understand his position, so you will know and understand why he lies to you, and you may tolerate it. However, you can decide to give him another chance or not.
In detecting whether he lies to you or not, you can see from the body language he shows to you. Try to see carefully his body language when he explains something to you. If he looks nervous or sweaty, or he does not stare at you when he talks to you, there is a big possibility that he lies to you.
Or when he often breaks his promise to you, you should be careful in detecting the reasons he gives. He may be dishonest. It means he cannot keep his own commitment to you, even in small things, because he breaks his promise to you.
Do not be panic, just calm when you find he lies to you. Try to reveal your mind and let him know what you feel, and try to get best solution for you both. Once again, he has a right to be forgiven, and you also have a right to give him another chance or not.
