Curator - need assistance to split off segment of tree

Hello Curator, I need help to remove the unmarried partner relationship between Ria Brodell and Georgie (Jenifer) Friedman (my daughter). I'd like the Brodell family tree to remain in tact to be managed by her father (Steve Brodell) and the tree I manage to stay in-tact. Please let me know if you can do that for me.  Thanks.
