Your W is definitely having an affair right now. You are plan B right now. Don't mistake the interest in your life and who you are talking to as anything other then she doesn't want anyone screwing up her plan B. Stop all affection and pursuit immediately. This type of behavior makes you look weak!
These sitches take a very long time to work themselves out. Right now you can't make things better but you can make them worse. Figure out what your boundaries are and set them.
Pretty big age gap between you and your W. How old is OM.
Fasten your seat belt because things tend to get worse before they get better.
