Just venting.

10 weeks from DD1. Yesterday he disclosed that she begged him to not leave her. That she said she'd do anything to keep him. That they had started their affair then he ended it. Then she started it back up with him and he continued the pursuit. The only reason it's ended is because I caught them. I already feel like the other woman. What do I even do with that. I don't think I can stay anymore. He's already ended it with her before. Who's to say they won't start it back up again, like before. Yes, we're in individual therapy and couples therapy. 2 weeks ago I considered staying but after hearing that, why should I. He had said that he told me everything but he lied, again. Why tell me that after I've said I think I'm going to give this a chance, again.
