I think you need time for yourself, as you said to get over the anger and resentment. It is great that your husband has changed for the better, but more often than not its too little too late. There are alot of women like you out there who put up with so much just because they want there marriage to work, but your husband put your life at risk a number of times and your childs and this too is disgusting. I dont know how anyone could let someone risk there lives and especially there childs and put up with this kind of behaviour, and get over it. I can undertand your disgust with your own behaviour. Im not atatcking you because i think finally you are where you should be and that is loving yourself enough to leave and start fresh. Find out who you are by yourself and see if your husband can maintain his commitment to your child without living with you guys. Perhaps you two will get back together, or perhaps not, take some time out for yourself. Because i personally think you outgrew your husband along time ago and now that you have got what you wanted you have finally allowed yourself to feel past your desire of simply loving him and wanting your marriage to work, and recognise all of these other feelings of which you have been supressing for a long time. Go out and find out what its like to be alone, and this will help you process these feelings, but i think the fact that your looking into legal separtaion and that you have doubts speak for itself. As someone once told me, there are no doubts with the one, and dont we all deserve to find the one. Good luck
