Unconditional love is loving someone even if you don't particularly like them. It does not mean unconditional trust or unconditionally accepting bad behaviour, a healthy mind will always place boundaries and rightly so. You are simply and purely loving someone with zero expectations. You are very lucky if someone loves you in this way. The notion that conditions A.B +C.. must be met to 'love' someone? think about that. Really think about it.
You see in the world what you carry in your heart...if it's lack of worth, you'll find people & situations that show your lack of worth. If it's unconditional love & self vale, you'll find exactly that reflected back at you.
