Yes, julia needs advice

I think telling her in just that fashion would be best. You've obviously thought this through, and you hit on all the major things involved with this crisis. Tell her that she's your friend, and you're worried about her. This should be said regardless of where you end up deciding to live.

The fact that she's beating her husband is bad, but if she reacts poorly when you tell her that it's unacceptable, then there may not be much that you alone can do for her. Does she have other friends, ones that might have seen her act violently before? An intervention shouldn't be out of the question. If this is really a pattern emerging, then the best thing you can do for yourself is to get out of that environment.

The dog situation should be secondary to how she acts towards her husband. Is the dog being fed and properly housed? If so, you can still point it out, but try to keep your tone even and non-accusatory. There may be an explanation for why she hasn't been paying it much attention. (including the depression you mentioned)

It sounds like you need someone nearby rather than distant to talk to about this. We might have a word or two that helps, but an informed opinion will be worth more to you than anything, I think. Talk to your friends. Stress the fact that this is really bothering you.

Jam it back in, in the dark.
