I'm with Sara. I think a boundary is being crossed. Just because you don't think W is interested in Santa, doesn't mean Santa isn't interested in W. It seems to me that W has had a problem discerning the meaning of attention from men in her previous "friendships".
More importantly, I think this is all a little too "in your face"" and probably sends a very confusing message to your daughters. They are vulnerable right now and don't need to deal with new complications. Mom going out with a "friend" of the opposite sex, considering what is happening in your marriage, is not a good idea right now. How convenient to call him a friend from church. Does that make it right? The other guys who floated in and out of W's life started out as harmless acquaintances,true? Perhaps the boundary needs to be redefined , spelled out so to speak, as to no socializing with people of the opposite sex while you two are still living together. And since I'm on a roll, how about throwing in there, "No sleepovers with annoying friends in what is still both of your house."
Have a great Easter, Frank. Remember what it symbolizes. Resurrection. A new life. A new beginning.
Peace,
