The reason I asked if they were exes is because I suspect the other party feels as though the time for that romantic relationship has come and gone. They've seen all they've had to see with the sitter (WOF). There's no surprise or anything new, hence the disinterest. Your sitter has become predictable in this person's eyes.
As far as combating the complacency, I have no idea. You'd really have to ask the cards if it's even possible to change the ex's mind. Because it may not be. Personally, I'm not keen on trying to get back together with exes, esp if that person is showing disinterest even after I've expressed my feelings. But that is my personal opinion, and I have no clue what's going on with your sitter and their situation.
I really agree with the first paragraph. I also agree with someone else who said they feel no sense of urgency to pursue a relationship.
The Wheel is about cycles we can't avoid unless we change our perspective. I always think, "Same sh*t different day" when I see the card. Sometimes when I see this card, I think someone is leaving too much up to fate and not realizing they can change things themselves.
I got this card a bit when I was in a relationship of breaking up and getting back together. It's like no matter how hard we would try, we would just resort to the same habits.
