Have you had any specialist counselling following the abusive relationship? Have you looked into the freedom programme, perhaps?
I think that it is well worth doing these things both to debrief your experience in the relationship, and perhaps address any previous messages or beliefs you held about relationships or yourself which allowed the early signs of abuse to go unnoticed. Please note I am NOT saying the abuse was your fault or that there is any reason he picked you, because abuse can happen to anyone, but sometimes there are factors in our past which can leave us more open to abuse, and it just makes us stronger and more empowered to know that we have dealt with those issues.
I have been in a relationship for coming up to 16 months now and struggling a bit, if I'm honest, not because my partner is abusive because he is not, he is probably the opposite in every way, encourages me to follow my own dreams and life path, gentle, kind, thoughtful, has never pressured or coerced me into anything, etc. But I still find it hard to have a normal relationship with him without being on my guard, worrying that something he said or did has a hidden meaning which I was supposed to "get" and he's going to be annoyed, worrying if he is ever in a bad mood that it's my fault, etc etc. I thought that I'd dealt with all my issues, but clearly I have not. And plus, I've been lucky, I recognise - he has been such a breath of fresh air compared to how XP was that I could have ended up with anyone 
and been grateful to them for being less awful than he was, which is not right. I'm looking into counselling now, which I hope will help with these issues, and I really wish that I'd done it before I had ever got into a relationship. I think that we tend to excuse our own experience and try to play down the damage that has been caused to us in order to convince ourselves that it wasn't that bad - but look at me, I'm 2.5 years on from the time I first realised I needed to leave and just over 2 years on from the time I did leave, and I'm just discovering some major issues coming seriously to the surface now.
I think that it would be really valuable, now you've come out of the initial shock period, the living day to day and re-learning how to live without control, to spend some time just focusing on you and what you want, rather than worrying about being single forever - if you can make your life as fulfilling as it can be, deal with any issues, work on your own insecurities etc, then anyone who comes along will have to be pretty damn special to disrupt that, and that's what you want. You want to be happy by yourself, and a relationship to be a bonus.
One site I've found really helpful and enlightening is www.baggagereclaim.co.uk. The articles on there are really good and just seem to get to the point in a brilliantly concise way.
