To cut a long story short. DPs father is trying his hardest to prove to police that his son is depressed so that they can get him "done" for something he actually hasn't done.
DPs sister actually did this "thing" and as his father would prefer to protect his sister he's trying to blame DP. (Much more too it but can't go into detail).
Police agree that DPs father is manipulative etc etc
They told DP yesterday that his father went through all of our belongings (whilst we were living with him) and found letters that we had wrote to each other that some how proved DP was depressed.
I feel sick that this man has been going through our stuff and read personal things of ours.
Is there anything we can do legally about this?
