crafty, I am with you on thinking about the experience lasting a life time. A week ago I TOO was ranting about wanting this ALL to just go away, and destroyed at the idea that i couldn't make any of it go away. I pretty much wrote everything in your last paragraph only a few days ago. Some here will testify to this too!
HOWEVER.... I AM going to therapy, I AM on the Freedom Programme, I DO have a network of online friends who have walked in the same style shoes as me, and I DO attend a local DV support group.
I have chucked a shit load of resources at this 'experience' and I can tell you that now that I have wraparound support for my fears, ramblings, wobbles and epiphanies, I am feeling stronger in myself.
I have just this last couple of weeks started online dating, and it's very early days, but it IS helping. I'm not sure I'm READY ready for a relationship, but I'm going really slow. I've had a coffee, it went well, but I'm not sure it'll lead to anything. There is another lovely guy that is interested/interesting too, we'll see what can be arranged meet up wise in January.
I spoke to X on Christmas Eve, a very emotional day for me prior to the call, once I had talked to him, I realised how much more detached I was, how his apologies and niceness had little or no impact on me. In one ear and out the next.
OK so I have worked HARD to get to that point, but you are VERY recently out of your relationship, you STILL need to go through the same phases I did, and we ALL do to get to the point where the past no longer poisons the future.
It won't go away, but it will stop mattering.
2012 is the year you PUT YOURSELF FIRST. You need to pull out all the stops to get yourself surrounded with safe support. Explain to the DP if you like, that this is not a slight on him, but that you need to explore stuff that he may find hard to hear, not about him, but about you and YOUR stuff, and that a neutral, trained person needs to be in place.
Go to your GP, ask about counselling, call WA and talk to them, they will have DV outreach workers, they will get you on the FP near you, it's free.
Thing is to remember love, that this monster put you here, but YOU are the only one that can get YOU back out. He will FOREVER be that sad little shit that forced you down so he could feel better. He will never change. You however will ALWAYS rise to the top. The fact he had to put you down to keep you there is proof of this.
