If you have the strength to call off a toxic relationship. Then, congratulation. I believe the greatest strength you have is self-love, or I rather say "myself is the most important person that I should take care of". You are succeeded in loving yourself more than anyone else.

When you are going to end the toxic relationship, you would like to ask so many questions. Meanwhile, sometimes, we already knew the answers. It's just our hope and ego, and us being delusional, that keep us thinking he/she might be changed to be a better person for us. Unfortunately, the answer is no. It's always been no. Only us failed seeing it. Poor us.
