Dont be ashamed of your feelings. Your love for her is valid. However, you are making decisions based on your emotions when you should be making decisions based on facts. Do her actions show that she is dedicated to you and not in an R with OW? Seems not. Therefore, act accordingly. Protect yourself emotionally. Drop the rope. Detach.
You would know and be certain your WW is dedicated to you and ended the R with OW because she would be chasing you and showing with her actions that there is no OW and that she wants to rebuild trust.
You know shes not telling the truth because you are still confused, hurt and on an emotional rollercoaster. Do you feel like that in a loyal committed relationship? No.
