If my boyfriend is a compulsive liar about things that are trivial should I break up with him ?

If he really doesn't realize when he does it, it might not be something he can help. He needs to figure out why he does this and if anything can be done about it. If he just tries to notice when he does it in the first place, he can then work on correcting himself and figuring out what he can do to stop. There is help for people that do this.

If it turns out that he's doing it knowingly, yeah. Probably best to distance yourself from someone like that. Especially if it's intentional. You've talk to him about it already. If he's not willing to do what he can to stop, it'll only cause you stress that you don't need. Maybe stay in contact with him, stay friends, try to help him, etc. but you need to worry about yourself, too. If all you do is worry about what's real and what's not with him, you'll never get to relax or be happy. He needs to understand that. If he truly loves you, he'll either understand and let you go or he'll do whatever it takes to stop.

In the past I had a 2 year relationship with a guy who lied all the time. Also about easy little things. Lying became so natural for him that he did it all the time, even about silly things that one should not need to lie about. The lies began to get bigger and lesser innocent and after a while that relationship got completely torn to pieces.Lying behavior is not good and if he keeps doing it, the lies can begin to get bigger and worse. You have to ask yourself, do you actually really know this guy? Try to sit down with him to have a decent talk about it. Maybe he isn't even really who you think he is, if lying goes so naturally for him. Honesty is one of the most important things in a relationship. If his behavior doesn't change, it's better to let go. Even though that's painful. If this continues you'll get hurt a lot more than you would if you let go.I hope you can work everything out with him and that it gets better.

If you know he is continually lying then surely you can't ever trust him in the future. It would be bad enough to be lying once but to be doing it as much as you are saying is horrible. You should think about whether you want to spend your life with someone that you will always be doubting. Is it worth it?

Yes YES YES and YES. Some people are compulsive liars and they cant help it. If thats the case then you need to go with him to a Counselling and it can really help him change his terrible habit. But lying in a relationship is a HUGE HUGE DEAL BREAKER. Relationships are built on trust and respect. If he cant respect you enough to tell you the truth about things then you should just move on. 2 years is a long time to be in a relationship and it isn't fair to you to go through so much emotional distress because of him. If you choose to stay with him you will start thinking that he lies about everything.. So once again if there is no respect for you in the relationship you CAN'T trust him.I know its hard and its a difficult pill to swallow. But some men often lie just to try to " not hurt you." They think that by lying to you about everything you normally wouldn't get mad about that you will be happier not knowing things that actually go on behind closed doors. But men never seem to grasp the concept of just being truthful. Some men do but a lot of men never really change.You need to think hard about if he is doing this for attention from everyone. Does he just like making up stories? Try to explain to him that if he continues this you won't be around for much longer.

I talked to him today about this issue. It was really difficult but we managed not to have a circular argument. He talked about how in his past he often lied to protect himself mentally. He tells me he's gotten better since then (though not entirely)... the habit that he got into started about 5-6 years ago. (we're both 19 now) He's a very reasonable guy and understands where I'm coming from. We concluded that both want to stay together. I told him I want to help him become a better man so I said I'd help him the entire way to simply improve on breaking this terrible habit of lying. I told him I'll understand if here and there he'll slip but so long and he won't give up on making progress I won't give up him.(I wish I could give the entire story to provide better understanding for everyone who has been so kind as to reply and help me with this lonesome issue. I thank you all for giving me the best advice you could based off of the information I provided.)
