In the realm of jerk. I have a lot of practice at that.
But, if she comes to you for help, only offer help with it comes to life threatening events. If she ask for water, give her a glass.
But if she starts, coming on to you or asking for money, respectfully decline. Show your strength, show her you won't be accepting every little thing she throws at your no more and will only accept, genuine, honest, and remorseful approaches. You are not her father, piggy bank, or bailout man. You are her husband and will only be accepting that position in her life.
Being a jerk, would you be telling her no to be spiteful. As long as you are not being revengeful or spiteful you are doing the what's best for you.
IMO, nothing you will say no to or will not accept she will take it easy or lightly. She will call you all kind of names, be prepared and holed your ground. You know what's right. Stand firm on your morals. Loving a person is not always easy, and it's not always about bailing them out, sometimes the hardest love we can provide is the love of letting a person go. Letting a person learn, letting a person fall. You will hurt through this process as well. It will hurt you to see her grow thru this.
Keep up the hardwork. That's why Sandi calls it hardwork, because it takes a lot.
