dp has one child, age 14 (let's call him L), and an ex. They live in the next village to us but used to live in the village we live in now.
when dp and I got together, dp's ex vowed she would never let L come and visit us, he was banned from our house. She confronted me in the street and said (in front of L) that I was a whore and a slag and had only won over dp because I was a tart etc. She called my children the most horrific names. She has admitted she does not want dp back (but clearly doesn't want him happy either!).
in the meantime, when dp wants to see L, he has to go around to their house and spends time there. Last time dp went there, the ex violently attacked him. When dp said he would not go around there again, dp's ex called in L and said 'look L, dp doesn't want to come here because he'd rather spend time with that whore and those bastard children'.
this weekend, dp arranged to go around at 9.30 and take L out. The night before, she called his mobile 72 times. She does this every day. Dp texted her saying what do you want and she wouldn't answer. He doesn't want to block her from his phone in case it is about L. She then started calling the landline incessantly until 3.30am at which point I unplugged it. I am calling BT today to get her blocked - the first call she uses her number but then she blocks it so you can't tell it's her but it is.
At 9.30, dp arrives at the house. She answers the door. She makes a coffee for them both. He goes to tell L to get ready as he isn't ready. He walks back to the kitchen and she picks up his cup of coffee and throws it against the wall and then takes a piece of the cup and tries to stab him. He wrestles her and she takes the piece and tries to stab herself instead and says she is going to kill herself as L is so rude to her now and she can't see the point in going on. She is also blackmailing dp with photos/texts from the past and threatening to publish them.
I think she is mentally unwell, seriously mentally unwell. I have always thought this. But unfortunately, no-one seems concerned about this other than me and dp. I am trying hard not to get involved because she hates me so much if she thought I was involved. Dp is concerned but is finding it hard to know what to do as she doesn't really want much to do with him but obviously he is very very concerned about L. I think L needs to go and stay somewhere else but unfortunately, he can't stay with us as he won't come near us. Her family won't speak to dp. Dp is going to call her best friend today and ask if she can go and stay there for a bit but she's abroad and this may not be a solution.
