Sorry, but it sounds to me like she is cake-eating. You get no physical intimacy, she continues contact, you pay all the bills? It might be time to set boundaries -- no contact, transparency. So what if she pitches a fit? You're either prepared to continue living a lie in a loveless marriage, hoping that the tide will turn. Or, you can stand up for yourself and ask for NC and transparency. If she's not willing to do that, then I think you will know for certain that she is choosing him over you, and just using you for convenience. It's hard but true. I'm just a newbie, but there are plenty of other threads that address NC and transparency in "piecing." Best of luck.
