my ex and I split when dd was 18 months due to controlling and violent behaviour. she turns 18 tomorrow.
for years he has made false allegations to social work, police and more that I am an abuser, ran a brothel. 
that was my favourite and more. my daughter was removed from my care for a week due to allegations but returned to me when they worked out what was going on.
when she was a baby he had me sectioned and made horrific allegations this led to me leaving.
yesterday he turned up at my door to rant about not being involved in her party this weekend. I dont talk to him but said to dd that if he wanted to come he could. this led to a temper tantrum from him about how selfish I am and that I didnt ask him to pay for half. the reality is I went no contact and he has only paid maintenance one year out of 16.
when he arrived I was at work this was likely intentional. I had spoken to his mum to say that I was heading to work but that I hoped she would come on Saturday. she and I never stopped talking.
he turned up at my door was yelling at my husband about how crap I was... how we didnt include him in her.party plans. hub thankfully defended it well and told himnto go away.
ex then said... oh I hear you're both pregnant. good luck with that. drewswife miscarried alot when she was with me.....
hub called me at work in tears checking I was ok. he is an emotional person and I managed to calm him down.
but I couldnt sleep last night and at 15 weeks pregnant was majorly freaked out. I have no way of knowing baby is ok until next weeks midwife appointment.
I am furious and want to scratch his car..... 
I dont know if im unreasonable or if I should just laugh it off. trust.me im trying. but watching Hannibal gave me some ideas for dispatching him.......
