what if you want to divorce your spouse and want to leave spouse and move out. Will that be considered abandonment or will I have to file seperation?

Your question requires more information and cannot be answered in this forum.  What constitutes desertion will be based on the individual facts in your case.  For example, if you left the home was it by agreement?  Did you have a justification for leaving, if there is no agreement? What circumstances motivated you to leave the home?  The answer to these questions is important and needs to be carefully discussed before an answer can be provided.  Lawyers.com offers general information and not legal advice.  Legal advice is based on the specific facts in your case, as applied to the existing law. I suggest that you confer with an experienced family lawyer, in your area to discuss this matter in greater detail. Most lawyers charge by the hour for an initial consult, therefore, please discuss fees upfront to avoid any misunderstandings.  Best of luck~
