WOW. Okay. First, stop referring you the OW as the BF. She is the OW now, even if it is just an EA. She can't be both. I don't mean to upset you, but as Starsky pointed out, how do you know what is and isn't in their relationship?
I assume she is still with her husband? This indicates an unwillingness to deprive herself of security until she is sure your H is going to do the same. And this has been at a standstill for almost a year? Anger towards you is shame towards oneself. Is he still supporting you and the kids?
I don't mean to sound pushy, but clarify a few points for the others on this Board, and we will be better able to help in anyway we can.
