Several of those statements are conflicting messages. That is very confusing!

I can understand your feelings of hurt and despair. It is hard to see your partner moving back, especially in a time of life when you need their support more than ever.
I hope that you both continue to go to couple's therapy and work towards improving the communication and working towards the hurt each of you has caused the other. It can take a lot of time to work through issues, especially if the pain is deep. Try to be patient with you wife. It's worth the effort, imo.
Best wishes to you two!
