Some lies are forgivable; others you cannot simply get over. You are not obligated to "forgive and forget" everyone's lies and mistakes. Even if you decide to end a relationship with a liar, it can sometimes be beneficial to confront him to let him know your feelings. In this case, you are confronting him not to encourage him to improve his behavior but rather to empower yourself and regain your confidence after a betrayal. You need to be certain, however, that you truly want to end the relationship. Do not use the threat of a break-up as a way to try to control his behavior. Sometimes a lie is just a lie. But sometimes lying behavior is linked to other, even more dangerous behaviors and conditions. Narcissists, abusers, overly jealous people, and obsessives are all more likely to exhibit pathological lying behaviors. Consider whether your partner has shown other concerning behaviors of late, such as possessiveness, jealousy, anger, or a lack of empathy. If so, you might not want to discuss his lies at all and instead simply exit the situation. Because you are ending the relationship, you do not need to determine whether or not he is still lying to you. You no longer care what he does: this conversation is all about you and your needs. This frees you from having to read his body language or maintain eye contact during an in-person conversation. All you have to do is say what you need to say, however you feel comfortable saying it. You can confront the liar:  In person. It will mostly likely be safest to do so in a public place. Consider telling a close friend or family member where this meeting will take place, so that you have back-up if the conversation escalates. This is a riskier option, but it also gives you the pleasure of seeing his face when you tell him that you know he lied to you. Over the phone. Consider writing yourself notes or bullet points so that you remember to cover everything you want to say. Remember: this will hopefully be the last time you contact him, so you don't want to leave...
