Oh gosh, you poor thing.
Don't EVER let someone tell you it was your fault, that you're lying, that you're making it up, that you deserved it, that you asked for it. EVER. There are people in this world who will say that and you just need to block that shit out.
The fact he doesn't see it as assault is disturbing. Almost like he sees you as this object to do with as he sees fit.
Coercion can often lead to assault. For me, in my mind, it's a very small step away.
I've been assaulted. It was awful.
I remember feeling just like you. Emotional, teary, confused, angry. The questions in my head were constantly whirring.
You do need someone to confide in and preferably it is a RASA counsellor. I had one and she was bloody brilliant. The first time I went to her I was just piecing together the fragments in my mind. It was so broken up, I just had feelings dominate me so it was like making chronological sense of things.
The second time, I hadn't quite dealt with everything that was causing me guilt. So, the second bout gave me the mental clarity and freedom from the guilt that had been weighing me down.
Continue to sleep in the spare room. Tell him if he does it again, you will be going to the police. You could go to the police now and they would form a case. Just because he's your partner, that doesn't make him exempt from the law regarding rape and sexual assault. If he says he doesn't think it was assault again, say "Okay I'll ring the police now and see what they say, shall I?" Watch his face... he fucking knows it is.
Have some space and time apart if you can. Please surround yourself with friends and family. You don't have to tell them intimate details but support is key here - it will feel like noone else understands what you are going through but you need people to lean on for a while.
We are here too. Speak to us. We will listen. We will hear you. We will advise you if you want us to.
Take some time off work if you can, too?
And finally, I want to give you a big fuzzy un-mumsnetty hug. Because I want you to know that no matter how fucking awful this has made you feel, people care about you, value you and love you. Proper soppy shit but it's TRUE and you need to hear it for when things might get a bit messed up in your head (they did in mine).
