Don’t count on them to always tell you what you are doing wrong. If you have offended them enough they might just fufill their end of the deal and then leave and ignore you. Or fufill their end of the deal in a way that fucks you over at the same time.
For example you wish for a certain girl to fall in love with you and she does but it is an obsessive love like a slave. She lives only to make you happy and becomes severely depressed and suicidal if she doesnt have everything “perfect” for you. Constantly asking if she is a “good girl” and if her life is worth living.
