Happy - Every time you write an update you surprise me by making me feel somehow prouder of you than I already was.
You did absolutely the right thing in calling the police. Do you still have your old sim card? If you do, you should definitely give it to them as evidence. All those texts he was sending you? Boy are they going to come back to bite him in the arse. Show them the e-mails and the messages - they will realise that this is perhaps even more serious than they thought.
Have you rang downstairs to tell them not to give out your room details to anybody? Please do that now if you haven't. It's better to be safe than sorry.
I really wish that you could see yourself through my eyes, so you could realise how impressive you are.
The dreams and nightmares - it sounds like it could be touching on post traumatic stress. That is absolutely normal in your circumstances. You have been through hell - you will probably need a professional to help you work through those feelings. It isn't worth trying to ignore them for a long time, as your brain needs to come to terms with what happened to you whilst you were abused. If there is any silver lining to it, these things normally start happening when the brain registers that it is safe to start processing. So parts of you have accepted that you are safe now, even if it doesn't feel like it just yet.
It's okay not to want to go to the refuge just yet, and of course you don't have to give us your reasons. But do please bear it in mind. They will be able to provide you protection until the police have done their work. At some point you should consider getting a restraining order put on him - maybe you could raise it when you speak with the police. That way, if, IF, he ever approaches you again he will be in deep deep shit.
You talking about your child sleeping through the night was beautiful.
