Maybe it's just me, and I hope I don't get flamed for this, but as much as my xabf put me through, I don't see a reason to play mind games with him, which is what I feel you just did to her. What purpose did it serve to hurt her back?
While I think it's great you have finally separated yourself from her, I can't imagine for my own sanity, kicking someone when they are down whether they deserved it or not.
If all you wanted was your property, there are many ways you could have gotten it back without accepting her invitation to spend the week together, then messing with her head for what seems to be your own selfish reasons.
Maybe my feelings are a result of having men mess with my head for the majority of my life. For now, I think you were wrong to do that.
