What is unconditional love? 

When someone treats you badly or abuse you. Then, in return, ask you to continue to love them because love should be unconditional. It is not true. 

Unconditional love is used for children only. A responsible adult who is in a healthy relationship know not to ask for unconditional love from his/her spouse. It is only used as an excuse to continue doing bad behaviors. Love is a privilege, not a right. Your love needs to be earned, not easily given.

Always love yourself first.
