Thank you so much for responding and for understanding.
GAG, yes D knows his plans, he spoke to her about it. He asked her when her spring break was because if it coincided with them going, he wanted her go too if she wanted to.
I would be less than honest if I didn't admit that part of this stems from my insecurity that D might find that she likes the ow and that she'll replace me with her just like her father did.
Now, I know that's the insecure part of me talking and the rational part knows that my bond with my D is very strong and that isn't likely to happen.
Unfortunately, this is an opportunity for D that I can't give her at this time. I wish I could. I will leave the decision up to D. If she goes, it will cause me pain, but I'm well practiced at hiding it from her.
Thank you all again for responding. I will do some more thinking and maybe I can come up with something fun to do together if she decides not to go.
