Returning to the Well
If you had a well in your backyard and every fifth or sixth time you got water from that well it made you very sick to drink, how many times would you go back and drink from the same well, hoping that one day it may change?
So in relationships, you have to have standards. Standards on respect, trust, peace, and love. Relationships take work sometimes and all of them have rough spots. But if you're being lied to, insulted, or let's just call it abuse of any kind, that's just not something you can tolerate. Be honest with yourself and potential or good times aside, has this person consistently demonstrated their willingness or ability to treat you with the most basic honesty and respect?
If not, it may be time to stop returning to that well.
