To me there’s 3 kinds of love
-conditional love: give only what you get
-masochist love: give no matter what, even if you are abused
-unconditional love: give freely, trust in the relationship. But maintain your boundaries - separate when you need to, temporarily or permanently.
The author mixes up the latter two. Unconditional means no conditions before you try to love the person. It means focusing on how things are going overall vs any individual day or moment. It doesn’t mean to keep loving them if they don’t return it.
