Husbands female friend blocked me on social media, but why?

Long story short. Through husband huge party for his bday and his female friend came. He spent the party with her until he tried whispering in her ear that she was his wife now. I was standing right there. Once he realized that he immediately went to sleep and the party slowly ended. After that night they continued to talk secretly and he would never mention her. Even texted the whole day of our anniversary. I was friends with her on FB and IG but just realized she blocked me on all platforms. I want to ask them both why. Am I wrong for feeling like there is something behind this?
