LP, I redoubled my efforts to build my relationship with my D13 (adopted from W's prior R / common-law).
Had a conversation that was a bit of a confrontation, because D13 was "pushing" me away. The end result was that we had an awesome heart to heart directly about the issue of the R D13 and I have and could loose, and that I'd never want to loose her. She simply said to me "you will never loose me..." And we both broke down in tears and hugged for about 5 minutes.
I think that was a turning point for us.
There's a million ways to do ONE thing. Figure out about half a dozen of those ways to strengthen your R with your D19. It will go a long, long, long way for both of you.
