I love my children unconditionally. Once I acknowledged that fact I stopped judging my son's lifestyle and my life improved dramatically.
I do not love my mother. There. It's said. That also makes life easier, as I stop having any expectations of my relationship with her.
I love H, but not unconditionally. Having survived one divorce I do not think I am capable of loving a man unconditionally. I have to keep a part of me safe from the repurcussions of another possible marriage breakdown, however much I love him.
Animals? yes, I love my cat, but it's not the same, I have a symbiotic relationship with my cat but it's not the same as a complex relationship such as the one I have with my son.
