Forgive him all you like, but I'm not sure I'd marry the guy.
Here's the thing: everybody lies sometimes. Yes you do. And so do you. And you. And you in the back row. We all do it. Little ones, mostly, but the occasional whopper. It's ok, we're human and sometimes lies are necessary for honorable reasons like sparing someone's feelings or protecting secrets. Other times we do it just to save our own ass. It happens.
You have to careful, though; lying can easily become a habit. It's often quicker and easier than telling the truth, and an attractive option to the lazy and self-serving. People can get so used to it that they do it even when they don't need to. They call this pathological lying, as in, you lie so damn much, you must be funked in the head, ese.
I won't call your fiance a pathological liar, but it sounds like he's definitely habitual. That's a huge red flag. His lies might not involve you now, but they will, sooner or later. The lies might be harmless for now, but that will change, too. Lies beget lies, and little lies beget big fatties. Like most bad habits, lying increases in frequency and intensity. Remember the words of those great prophets, the Thompson Twins: "Lies, lies, lies, yeah. They gonna get you."
Don't underestimate the importance of trust in a relationship. It's huge. Especially when you don't have it. And you don't have it right now, with good reason, so I'd be very careful about going any further with Sir Lies-A-Lot until you nip this problem in the bud.
Talk to the boy. Tell him his lying concerns you. He won't like it, but tough titties, you might marry this guy. Find out why he does it and how he intends to stop, because he needs to stop before you go any further. Otherwise, his lies, yeah, they gonna get you.
Thus speaketh the Wise-Ass.
You say you've caught him in a "bunch of lies." Based on that, I would probably start questioning and wondering about just about everything that he says. If he has a known history of lying, it would be difficult to trust 100% that he is being honest and upfront with you. I say you should proceed very cautiously if you plan on keeping him in your future. I also agree that you really need to sit down with him and talk it out.
Sorry, guys, I'm taking a hard stance on this one. He's lied before. You've caught him in a "bunch of lies". You don't know what else there is that he's lying about that you just haven't caught yet. And speaking of catching something... Who knows how long it'll be 'til that happens.
You say you love him. How can you tell since you don't even know who the real guy is? He's a liar. Dump him now!
hmmm lies from a significant other? This is one of those things that I believe creates GOLIATH sized insecurities in the relationship. He needs to see that and know how his lies have manifested themselves in your relationship.
Now as Cary said we all lie at times....so it is for you to determine how substantial the lies are and how you want to handle it.
Me, I am more of a forgive and forget type unless it happens again. Well, them I am more of a forget him and dump him type.
Good luck...sadly when we love someone we take a lot more crap than we would from someone else.
Wise-Ass is right on with this answer. Do some serious thinking and questioning before going any further with this man.
I made the mistake of marrying a liar in my dumber days and found out the hard way 3 years later that everything he told me about his past was a big fat lie. He was in the Navy and stationed near where I lived when we met. We dated for a little over a year and lived together for about 6 months before we got married. I finally got to meet his family about a year after that. I found out totally by accident about his lies and not wanting to believe he would do this to me, I started asking very direct questions of people in his family and of his childhood friends. Once I got a good idea of how bad things were, I confronted him with it all and asked him to please explain the differences in stories (gave him a chance to come clean). His only response was, "they are all liars and it is a conspiracy against me." He called his own mother, sister, and father liars but refused to sit down with all of us together and straighten out the differing stories or to even say they were liars to thier faces. I realized then that I had been married to a man for 3 yrs I knew absolutely nothing about. My basic trust in this man to always love me, never to physically hurt me, and to always be faithful was completely gone. I left the marriage soon after and have never regretted it since. I do, however, feel sorry for his current wife whom he is doing the same thing to now.
I BEG you to rethink your entire relationship with this man before it gets even more serious. Put your own safety first as you never know what ELSE he may have lied about.
My former fiance was like that. He lied about everything, even his education and sexual orientation. I found out he was a college drop-out, in the closet gay man who would say or do anything to get what he wanted, which was a free ride in life.
Give the guy a chance to come clean. If he doesn't, dump him.
my first husband lied about everything. my soon to be ex(number 2) is a selective liar which is sometimes worse cuz you don't see it coming. just broke up with a guy who told me he never had sex outside of his marriage, well it turns out they were swingers. I won't put up with lying ever again. I am now seeing a nice guy that believes honesty and trust is a cornerstone for a relationship. we have been out 3 times. I hope he is for real. time will tell. run, run, run. I know it is hard to walk away when you are in love, but you don't know who you are in love with if it is all b.s. the heartache comes later....financial issues, cheating you name it.
