Past relationship affecting the way I think in this relationship, advice please?

I am 27 and have been in a relationship with my partner for two years. Prior to this I was in an abusive relationship for 4years. The physical abuse I have got over but the mental abuse and how it affected my self esteem seems to be creeping in and affecting my current relationship. My partner now is the best BF I could wish for, he was fully aware of what I went through before, i told him when we met just so he knew that I may have the occasional wobble. Recently my BF has been demonstrating traits similar to my ex (not the abuse) but generally being a bit lazy round the house, not spending any quality with me and I have been feeling like I have being taken for granted. This has sent alarm bells ringing that he is going to start acting like my ex even though he isn't like him at all. I have taken the first steps to stop this affecting my relationship by talking With my partner about my feelings, he was a bit shocked as he thought everything was fine. I guess now I have told him how I feel then its up to us both to improve things. I love him so much but don't want to be a doormat ever again. Have I done the right thing by bringing it up how I feel? s now I feel a bit vulnerable and exposed?
