My best friend's (F28) husband (M31) is pushing her to be more sexual. I think I might have contributed to the problem.

I don't know what to do. I feel partially responsible and I don't want to lose my best friend. We've been friends for almost 10 years.<br><br>My best friend "Elaine" (F28) is a very sweet, innocent, and caring person. When we were younger, she used to confide in me about a lot of personal things, including her sex life and sex drive. She's never been very sexual, which has been a problem between her and her husband "Dale" (M31) for quite some time. I think I might have inadvertently contributed to Dale's frustration. I'd love some advice on how I can help them work through this.<br><br>About a year ago, Dale and I started talking about a business idea we have together. Because of that, we've grown closer, and he's now a close friend of mine too. Dale knows that Elaine and I are close, so he's started confiding in me about their sexual problems. Honestly, he complains a lot to me about how he wishes she was more sexual. At first, I didn't want to know about their personal issues and told him that. But he seemed so stressed and distressed that I wanted to help. Now, I regret it because I think Dale is starting to see me as an ideal for Elaine.<br><br>Apparently, a couple of nights ago, they had an argument about sex again. After almost 6 years of marriage, Dale is wishing that Elaine was more sexually adventurous, since he's more of a sexual person. I don't know exactly how the argument went, but Dale told me that he said something like, "Even our friend is more sexual than you. Imagine if you were as sexual as her... we would have a great time"<br><br>Ever since, Elaine hasn't been answering my calls. I'm worried that she might think I've been having some kind of affair with Dale or at the very least, that I've been fueling his sexual frustrations. I don't know how to fix this. I feel terrible. Part of me wants to talk to Dale and ask him to fix it, but another part of me realizes this isn't his problem. I don't know what to do. I wanted to anonymously post about this here before talking to either of them. Any advice would be greatly appreciated.<br><br>&#x200B;<br><br>TL;DR: I think I inadvertently caused my best friend's husband to see me as an ideal for her in bed and she's not calling me back after he told her that. I feel terrible. What do I do?
