1) UNCONDITIONAL LOVE is something that is WITHIN US (internal state) not WITHOUT US (external state) or OUTSIDE OF US (external state).
No one can cause us to feel unconditionally loved. Only we can create that internal state within ourselves. Only we can experience it. We may think it is because of another person but really, all the other person does is give us perceived permission to feel a certain way. This is how we justify creating a blissful internal state.
A state is a moment in time and we are dynamic individuals. So this blissful state is going to change from one moment to the next. This is whether or not the other person changes or how they feel about us changes.
