yes honey you don't need to be adding any stress in to your already very stressful life Johanna has a good point there,maybe you feel you need to be there for your sister, i can well understand that and maybe the break from your husband might do you both some good, but think hard on it before making the decision to leave, the same problems will still be there waiting for you when you get back, but it might give you both some time to reflect on the situation, i guess only you can decide what is best for you and your relationship right now.

Tell me what does your husband mean by your pissy attitude, i am not really sure what that term means, or what he means by it, do you yourself think he is right?

I can only wish you well and hope that things improve,both emotionally and financially and soon,take care and hugs and remember i am here for you.
