Do men regret cheating and leaving their wife? ☹💔

My husband left me for another younger woman whom he met at work and barely knows and got her pregnant after 13 years of being together. We have been together since we were 15 years old. I'm devastated and depressed. We have 3 children together. We used to fight all the time but just when things were getting much better, credit scores were going up, and building he pulled this :/. Now, literally both of us are financially struggling. He is being stubborn and is already living with her. He doesn't want to divorce me though because he says he doesn't know the future and we may end up together??? I don't understand but he seems so confused and unfortunately I still love him. I know I deserve better though. Do men ever regret.?????? I want to have the satisfaction that he will one day soon 💔💔💔💔
