Pink: I'm soon-to-be 55, not that it matters since I am close in age to you. My ex left when our daughter went off to college - wasn't happy for the last half of the marriage, threatened to leave 4 times, has Asperger's Autism (not his fault, I know, but he prefers to be living alone). My advice, if you would be open to it, is to get a consultation with a Family Lawyer. Sometimes the first visit is free.
