It's important to stop and think about that distinction, as you say Bagitha. I think the thing that then really hurts is to discover that it really is meant to hurt and has been done with malice in mind. For example, my ex-DIL stopped my son seeing their son (my grandson) the day after she learned that my son had met someone and had started dating - he had let her know as a courtesy, unfortunately. In no way did it impinge on his relationship with his son. They had set a pattern of my grandson staying over with his dad three times a week, in his new home just 500 yards away so he could be with his son as often as possible and take him to school. The next morning, ex-DIL put a new profile picture on Facebook, showing the title of a book called 'Revenge is Sweet.' It was five months before he saw his son again (that meant I didn't see him), and after access was re-established via her solicitor (shows whose side solicitor is really on), ex-DIL withdrew contact again the week before Christmas, telling my son to send all the Christmas presents with someone else (he did).
I think that is unforgiveable behaviour. I have risen aboove it and contacted her to ask if I can see my grandson, and was able to see him for 10 minutes a few days ago, because I picked him up from school while mum was out. It took three requests before she capitulated. We have to work our way to my son being able to see him again as previously, which is what my grandson wants. I don't feel malice towards her, just want her to stop it and move on - she has a new boyfriend who is practically living in my son's house now, and spending time with grandson. She just doesn't want my son to be with anyone, and has threatened him that she will take him down and screw him into the ground.
Do you forgive continuing nasty behaviour that is designed to cause such pain? She won't stop, so it's something that is hard to let go when it's being thrown back at you again and again. I just want her in the background, not causing harm and then I can move on myself.
