I don't see it as a setback, it is totally normal for a WAS to run hot and cold during piecing. Heck, people run hot and cold even in healthy marriages. But especially in piecing, because the WAS starts thinking maybe the LBS is getting too comfortable with things and so they feel the need to push the LBS away. The thing to do during these episodes is first, remain calm Second, give the WAS all the time and space they want, and don't make a big deal out of it. She wants to see her friend and not go with you to a family outing? Well you think that's a GREAT idea!! You think the two of you could use some time apart, and frankly you LOVE the idea of hanging out with the family by yourself! This does two things. First it gives her the time and space she wants. Second it makes her wonder why you're so eager to give her time and space, what are you up to? Why are you so happy being independent of her? Is there someone else at this family outing that you want to see without her around? It's DB'ing 101, be mysterious, have PMA, be strong and independent. That's what attracts the WAS back and it's what keeps them from straying too far.
