I haven't been through this, however, there's a couple of things I'd like to let you know about -
firstly, I don't know what kind of meetings your daughter is attending,
but the finest friendships I've ever made and keep are the ones I've made in Alcoholics Anonymous.
However, that said - you are right, in my opinion,
to be suspicious of male - female sudden
intense relationships in early recovery.
I've heard these called 'jitter house romances'
and they are always short lived, and caustic.
I can't advise you on the whole present thing,
but I hope you find the support and wisdom
you seek here at SR.
