Trigger - csa

I managed to break away from my abuser 3 years ago. I had felt trapped in an obligatory relationship with this person for years, but once my intense flashbacks started I could no longer pretend all of it didn't happen. I have made it very clear through my actions that I want no more contact with them. Due to the situation, which I won't go into detail about here, it has been a great challenge to ensure I don't 'run into' this person and it's been difficult to get others in my family to understand my reluctance to have anything to do with this person. 3 years on, I thought I was able to rid this person from my life. But, this Christmas, I was sent a present from my abuser. I found this really triggering. I don't want it. I can't open it. Yet I can't seem to throw it out. EverytimeI see it I get triggered. I feel like I want bring it to t with me and talk about it. Would you? Also WHY is this person sending me a Christmas present? Is it to taunt me?
