Lying causes a break down in communication of private information, thus causing said couple to move apart through not talking, and eventually causing them to split up.
Talk to him and tell him that you don't like it when he is lying. If he wants your relationship to work, you and him should build it on trust and honesty. If he lies, you will lose your trust on him, and it may ruin the harmony of your relationship.
It will ruin our friend like relationship
There is no reason why it should
I would suggest trying to tell the other partner in the relationship, and try finding out why the people are trying to ruin your relationship, talk to them see whats up!
No I would not at all because if she is lying she does not want you
It can if you have a lot of baggage.
A headache.... (jk)
It can ruin relashonships and can cause stress knowing you did somthing horrible behind someones back.
if you have your relationship status on facebook as "in a relationship" but it doesn't say with who, then your freakin lying
Don't go there! He is going out with your best friend. But then maybe you to belong together as you both are lying to her.
It doesn't have to ruin it because he will get leave (which is 30 days of vacation) every year
Tell him/her that all sound relationships depend on mutual (two-way) trust and honesty. Lying is often a recipe for wrecking a relationship. If the lying continues, end the relationship.
