It must be horrible for you, having to wait until Monday to finish the process. It has to be done now though - too late to go back. From what you say, it sounds as if you have made a balanced decision, if your relationship is turbulent. You may indeed regret it but you have to do what is right for you at the time; if you had continued with the pregnancy, you might have found yourself regretting that too, if your circumstances changed. I wish you well.
