Why do guys lie so much?

I don't know if he's cheating or not, but if he's lying each time, do you really think you will be able to trust him in the long run? I've had my trust broken, and trust me it takes a lot of time and wounds to heal to trust someone again. Don't make him your world if he's a liar. I don't know how long you guys have dated or anything, but there IS a chance there is a lot you don't know about him. I'm sorry I had to say this. But when we love someone, we can't see that person doing bad. However, here, you've got proof he's done you wrong, red flags are waving. PLEASE for your own sake, confront him. Judge his body language based on the confrontation and then decide where to take the relationship. Best of luck!
