Walking Away From Abusers
There is no person you have to tolerate or put up with and if you think you do, you are more into self-abuse than you are self-love.
Self-love requires us to respect ourselves enough not to tolerate the unacceptable behavior of others.
When you put up with the unacceptable behavior of another you becomes that person's ENABLER.
You are not helping them in the slightest to become a more loving person, you are helping them to become a worse person by keeping that person in your life. Sometimes the best gift you can give to another person is to walk away them so they understand that abusing and disrespect people does not win friends and influence people, it pushes people away from them.
