That's fine Buffalo. Actually, that's great! You did what you felt was best for you and, for your son.
BTW, I noticed you made reference to the fact that he "physically hurt you". In situations like that, even if it happens only once, I'd like to suggest that you read the stickies at the top re: ABUSE! It might be a good idea to educate yourself on that subject as well. There are also domestic violence hotline numbers that you can call and talk to a 'live person'...someone that is knowledgeable and can give you their input. Knowledge is power!
I know this was difficult for you!!
