Life is too short to allow this kind of bullshit to happen to you – what will you get from believing a cheater anyway? You want kids and he doesnt. Someday this cycle cummulates into marriage and a kid does happen, can you ever be sure he will be the kind of person who wont lie to you again and you have to keep saying sorry? Yes people can change but he has done this repeatedly and his ideals dont match with yours. And jeez. This whole no one can love you more shit is typical of exes who want to get you back in your weak, post break up state. I heard the exact same lines and guess what, he was flirting with my friend that whole time. Dont allow such bad treatment just because you want to be in love and want a family – its worth waiting for the right partner any day! Sure you are going to cry, feel angry and lost but that is not how life will be forever – you have your own self-respect too and someday you will find that wonderful guy you actually deserve, this one doesnt and its time you accept that.
