Q&A Should I Ask about the Physical Parts of the Affair?

Please help me Rick. We are 15 months from D-Day I'm doing well for the most part, our marriage is starting to thrive and become better than ever, but I cannot get past the physical part. I cannot get past the fact that my husband was intimate with another woman. I can't seem to move on from that and it hurts so much every day. How do I get that out of my head? How do I move past that and start to see the light at the end of the tunnel? I feel like there are still questions about the physical part of their relationship that I didn't ask early on but want to now. Should I or is it too late for that? What do I do?
