She Is Mine To Love, The Way She Is

I have been married twenty plus years. My husband has had special relationship with a queer woman for fifteen years and two children with her. She can't manage a relationship and falls back on him, we practically support her and her children. I used to get angry, but I don't any more, I am just happy I don't have her burden and realize I am her mother, sister, best friend. She lives with us right now, again, following her latest breakup, her children have lived with me full time all their lives. My husband loves her in a way I don't understand, he will walk to the ends of the earth for her. I really don't know if she comes to bed with us to be loved by him or to be loved by me.

I am not her lover, at times she is my husband's, but night after night she sleeps deep in my arms. My anxiety is when she meets a woman and loses her composure over her, until she is hurt and I hold her again.
