[t.D.A.]

I will add:
Expecting the other person to do everything i.e. be responsible for your happiness, peace of mind, satisfaction etc etc especially if you're not putting anything into the relationship.

In my opinion when women hold on to issues even though they claim to have forgiven, it's usually based on a fear that they will do it again. It's your way of trying to control the situation and ensure he/she doesn't do it again using anger and threats.
