Interesting and true concept, however I choose to live with an open heart and let in whomever if they choose to hurt me that's their problem and issue not mine. My heart is open and will remain that way. Live for love
Words to Live by as I have Learned long ago you CANNOT change another person; it is enough of a struggle to authentically change yourself yet alone trying to change someone else. Focus on being you - that is challenge enough.
Because I need to,prove to someone that I wont hurt them like I hurt almost everyone in my life. And honestly everyone has messed me up and im insecure and doubtful towards friendships and relationships
