Yeah strange, but update, it all makes sense now. After she concluded business with my husband (ie bought a painting), she began messaging him incessantly. We're talking 10-12 times a day, going on about her life and this and that. She sent me a friend request.
So now it makes sense, she's taken a liking to my husband and she figured she could throw me off the scent. Please, honey, I may have been born at night, but it sure as hell wasn't last night. 😃
