Peter, I understand because my H also gives me hope and then takes it away. But the way you're reacting is not working so you have to try and change it, even though it's not fair and you feel like you're being used. Believe me, I get it.
Sometimes, I get so angry that my H makes this all about him when he's hardly been the perfect H. But until we're in piecing, it is about them.
Next time as much as it kills you, just tell her to have a good time. I bet that will shock her. And it would certainly be a 180.
