You have to accept that he is the problem. Your methods have taken on the responsibility for this on yourself. You can't be what he wants if he is a cheater who has disregarded all of your efforts. The key now is to accept that you are not a loser and you are not the problem. What he has done is make you the problem but you can't behave or feel that way as well. He has taken a relationship and trashed it. That is all him! He may want children but it isn't about that. It is about him sowing his oats with a 20 something. He will probably wake up one day with kids at his heels and realize that he is a horrible person. When you take on everything then he takes on nothing.
She may get pregnant, but what if he loses interest in her. He is capable of this. Sometimes the mistress is the one looking very stupid. You have to find someone to talk to because this is rocking your self confidence. You deserve a honest healthy relationship who is dedicated to you. He isn't it anymore. Find someone to talk to and move away from the impact this is having on your life. You deserve a faithful person
