I'm sorry but I am bit ( A lot) confused about your thought process.

Yes she hurt you .. But she can do anything she wants whether you accept or agree with it.

Talk of about getting her into the kitchen, You can then ask her anything you want???? You do realize she doesn't owe you an answer or anything .... and your also wanting to show her that you have become what SHE always wanted to be??? I don't see how any of this can help you in any way shape or form.

Your were together and then broke up .. It happens all the time, I dont know anyone that hasn't gone through a breakup. I think maybe seeing a Therapist would be helpful in you learning how to let go and move forward in your life.

Good luck
