You will enjoy it more than she expects.
Your wife's best friend never liked you much, and has never hidden the fact that she thinks your wife is too good for you -- and that she would have much preferred it if your wife had dated her brother-in-law. So what really scares you about this message is that you know your wife's best friend would love it if your wife eventually left you to be with him.

You wish you were better able to satisfy her sexually – but you can’t, so she’s right about the fact that you do feel some degree of relief that she now has someone else to fulfill those needs for her.
