Hi there, be strong, you may have feelings for him still and you feel you'll never meet anyone like him, hopefully you won't, people like him never change, they give the sob story of they'll never do it again it was a one off(3 times in his case) how everything will change, but you'll never trust him again, you'll always wonder what he's doing when not with you and that's no good to live your life like that hun, there is always a choice in life, and there's always someone better than this guy, deal with your sadness and move on, he needs to confront how he treats women as much as you need to deal with the end of a relationship, go live your life, believe me life really is to short to have a partner you really won't ever in your heart trust again, so paint on that smile, look at what you do have in your life and move on, good luck hun
