Should he leave or should he stay?

I have a male friend that I believe is in a toxic relationship. They've been together for three years now. In short, they briefly split up and they had a disagreement about custody over the dog. She also had an argument with his brother and tried to psychically hurt his brother. She got sour that he didn't take her side and that she didn't get the dog, and she went and falsely accused him of abuse and got him arrested, all because she couldn't get her way. He was able to disapprove her case. They were split up for 8 month and she wants him back now. He took her back. She claims she was raped in the period they were apart, but I feel like it's an manipulation technique. I'm telling him that that bitch is crazy. And up next she's going to try and trap him with pregnancy and marriage. Low and be hold, now she's hinting she wants a kid. He swears high and low that she is not that type and won't do that to him. I think he is being stupid. I told him that he is just taking her back bc she's a comfort zone and he isn't in the mood to start over with a new relationship. Which he admitted, but he also claims that she is pretty and he loves her. He's struggling with forgiving her, but holding on bc he loves her. Am I the one wrong in this situation? Should he stay with her? Should he give her another chance? Is she trying to trap him? What do you think? What would you have done?
