It wasn't clear to me what had happened to you but if it was something that was physically (or mentally) abusive, then you had to end it if you are to value yourself. Habit is so powerful that it makes us do things that we don't really want to do. We underestimate it. It sounds like you've done the right thing. If it didn't feel strange right now, then you haven't invested any feeling into the relationship. But the power of the 'habit' will dissipate soon. There is a lag between the action we take, and the habit's withdrawal symptoms. Good luck. :-)
