I would say to you that you are lucky that you found out what a total jerk he is and you will have a better future because of it. I no it does not feel that way right now, and the hurt is out of this world. But, if you knew who he really was all this time, would you have wanted him anyway? No, I doubt it. People wear many faces for many reasons. You are blessed to have found this out now and not after you married the jerk and had a couple kids. You are free to find the right guy and if you had stayed with that jerk, you never would have. Do not give this loser anymore of your self. He is not worth it.
Although he has cheated, sooner or later his conscience will catch up with him, especially when something negative will happen to him, but I agree, he didn't care about your emotions or how his infidelity made you feel and hurt you, so he is very selfish and putting himself first and above everyone, so you step back and out and let him think twice on the pain he has caused, because it will catch up to him.
We are humans and although at the moment we don't think, it will catch up to him sooner or later and he will be sorry, but probably too proud to say it. It doesn't mean that he won't turn around and do it again, so walk away and don't look back. He's not worth your love and you deserve to be treated with dignity and respect.
He's saying that to make you feel better and there's a tiny possibility he's saying it to keep you dangling just in case he wants to come back again. He's not a good guy.
Not sure that I care, just wondered as he is always saying he will regret it!
Don't worry about how he is feeling, worry about how you are feeling. I'm sure deep down he does miss you but it's not enough to want to be with you. He made his decision. So take it for what it is and try not to think about what he's doing or how he's feeling. It's not worth your time and energy because he wasn't thinking about how his actions would affect you or her.
Bit of an odd question, but how do you think that he is feeling right now?
