Purple, by now I hope you have gotten in touch with someone - whether victim support or rape crisis, and are getting some help. Well done on calling the police, unbelievably brave of you and must have been so hard to do.
Remember, he does not do this because you deserve it, are horrible etc. and you are not, of course) he does it because HE is abusive, nothing to do with you, you just happen to have been unlucky enough to have been in his path for a while, but you are being so strong and doing and have been doing all you can to get him out of your life, and it may not feel like it now, but you are being so strong and brave and I applaud you.
Please believe you deserve goodness and kindness and take all the support and help that comes your way, from police, courts etc. I'm not UK-based sorry so don't know of the agencies that could help, but others do, and you are so deserving of it and strong to have kept going after the death of your mum, your DD, and through all this.
