Just remember that he is the jerk. Certainly, when somebody have bullied and controlled you, you get into the habit of being unsure over doing anything on your own. That is how those types get such control over you. You are not alone in this, and it is not your fault.
Take your time and heal up. It is like a broken leg; you are not up and walking again the next day. You are worn out and stressed, but I must congratulate you on taking charge of your own life. You are doing just the right thing in looking at the big picture and decide what is best for you and the little one.
I am impressed with the strengt you showed and I am sure that you will get back on your feet soon, simply because you have decided to do so. You have shown more strengt in this situation than many others could have. You can be proud of that.
So hang in there and just work on caring for yourself. Remember that you are the one with the personal worth, while he is the ^%$#%$#^
