Yes, you can. Do you want to be with a liar who does not want to be with you? Probably not? His lying is his choice and not about you at all. Whether he wants to be with you or not, you don't want to be with him! You only get a say in what you want, not in what anyone else wants or does not want. You don't want to be with your trash collector do you? Are his/her/their feelings hurt about that? Probably not Learn to see things outside of you as not about you and work on not taking events that happen personally. This person does not want to be with you. Fine/who cares? You use to enjoy being with him but then he turned into a smuck and lied to you, etc. so now you do not enjoy being with him. How dare he lie to you?! Find your "angry" at his mistreatment of you and let that help you instead of wishing for what cannot be (him not to have lied).
