I know how you feel. While I didn't have a child at the time, I too was in a physically, mentally and emotionally abusive relationship a little while ago.
Your fiance sounds to me like a very weak man (if you could call him that) that has a problem that YOU can not fix or change. My ex was the same. He always threatened to kill me or my family but in the end he was the one who he tried it on (he is still alive but is a manic depressant). I too thought I could help him but when people are like this only professionals can help and only if they want them too.
You really need to GET OUT of that place NOW!! If you do leave or he leaves you what is really the worst that could happen? You and your son will be safe. You really need to think what's best for your son right now. Don't worry what your fiance is doing or wants.....when was the last time he worried about you? It may take a long time but getting away from him is the best thing you can do for yourself and your son. You need to sort yourself out to make sure you can be the best mummy you can be for your son. You need to stand up for yourself and your son (he needs you too) Picture if your heart what you want for yourself and your son. If you put your fiance in this picture is it as nice and happy (truly)? I'm sure you already know in your heart what is the best for you and your son but you just have to be brave and strong and get out now and start a fresh new life. Use every resource out there to get what you want and need. Don't be afraid to ask for help. Please be strong if not for yourself but for your son.

You'll find you will come out of this a lot stronger person and karma will work the rest out. smile
