Divorce in general

What would be the first thing to do before “the cat is out of the bag” so to speak?
Should I set up another residence and move out while still married? My husband is very likely to get angry and not respond well to a divorce so I need to have things already done and taken care of so I am not scrambling for our basic needs. I fear he will see the bill for a consult and ruin my preparation time. I am a dependant spouse andI am trying to squirrel away $ to survive and cannot spend hundreds on a consult as of yet. Bottom line is What do I need to do now before he knows what I have in mind?

Every situation is different, and you really should set up a consultation with an attorney before you do anything. The attorney can help you develop a plan of action based on the circumstances in your case.
