I have been married for 37yrs my husband had fell in love with someone else and is planning to move in with her. Am I entitled to spousal support?

Lawyers.com offer general information and not legal advice.  You are seeking legal advice, which cannot be provided in this forum and will require a complete review of the facts in your case.  As a general rule, the grant or denial of spousal support is totally discretionary with the court.  The judge will review all relevant facts in the case and make a decision by applying the applicable law to those facts. For example, what is your age?  What is the status of your physical and mental health? What is your earning capacity, education and work history? Did you work during the marriage?  What was your standard of living during the marriage, etc? The court will carefully consider all of the relevant statutory factors and then make a decision based upon your needs and your spouse's ability to pay. In order to protect your interest, I recommend that you meet with an experienced family lawyer in your area to discuss the significant facts in your case, so you can make an informed decision regarding your overall best interest.  Please note that most lawyers charge by the hour.  The consultations may be based upon the lawyer's hourly rate.  Therefore, you need to discuss fees and costs for the initial consult in advance of the meeting to avoid any confusion or misunderstanding.  Best of luck~
