I can relate to your conflicting feelings since my husband did come back the first time and I didn't trust him despite letting him back (my fault). It's truly hard to love someone the same way when you've been betrayed. It sounds like she came back recently so there's no need to rush. Maybe you could even take a little break from seeing her to think on your own. But if someone messes up and they're truly sorry and will do anything to fix it I believe they are worth a second chance after slowly earning your trust back, especially if you and your wife were doing well up she went off the deep end. The thing is there is a risk involved with taking her back, just as there is a risk with anyone, so I guess you have to be willing to accept the risk as well as manage your feelings about her betrayal in a way that doesn't repeatedly punish her forever. I kept punishing my husband for two years after he back and he was still wrong to leave again but I do believe the endless punishment reflected badly on my part and I was wrong to do that.
It's still a success story to read that your ex-wife came back and that you have the option of trying again with her. I really do hope it works out!
