Not have much to go on but a few sentences I'd say you have several relationship issues all run parallel. 9 plus year of history, communication issues, your place on the totem pole, her dishonesty and cheating and lastly her new found bi sexuality.
I would suggest marriage counseling to work through the first 4. The open marriage and or poly would be the last thing.
You might want to do a very in depth look into the past... cheaters and cheating can be a pattern and coming clean doesn't always happen without proof. This might not be the first time ....hense the reason your on the bottom of the totem pole.
Do you have kids or are there kids involved ?
The decision to go forward after such a betrayal is a little surprising ....and not responding to texts and calls sounds like she's checked out .... a red flag to me...so hope for the best and plan for the worst.
Good luck. D
