As an update, things improved in the evening. I used tips I found here. I kept the conversation light and did not engage in anything bordering on arguing. I was very agreeable without being too needy. An example was when she said she hadn't slept with anyone and I fought the urge to ask probing questions.
She ended up sleeping in our bed. This morning we talked about going on a date Friday night. It also helped that she got her car stuck this morning and I let her use my car while I stayed behind to fix the situation.
I'm trying everything in my power to keep things positive and not bring up anything that would seem critical. I feel torn because I do not want to divorce, but I don't want her to continue with her behaviors toward other people. I guess I need to hold off on that for now. My hope is that if I rebuild the marriage, she won't want to engage in that behavior anymore. Thank you everyone for your replies.
