Hi Lonelee, I'm in a way in the same situation as you. H having an affair for 2 years, saying he wasn't happy. Nor was I, but he refused to communicate. We even went to see MC while his affair was going on ( when we went I didn't even know another woman was on the scene, but now I can see why it couldn't work!).
I'm not an expert but from where I stand why would he come back fully to you when he has sexual intercourse with you and her? So far there is no consequence for his actions! My H knew that if he went back to OW, we'll be done (that's what I thought but my heart says differently), and I knocked him out 4 months ago.
On the other hand, you are putting your health at risk. Get yourself check and stop sleeping with him. He is having the best of both world, why would he change the dynamic?
