3. Do you have any close friends or family nearby who you can lean on today? You need support from "someone with skin on" as my granddaughter would say.
Just want to underscore again:
Really, call a lawyer. Ask friends who have been divorced or separated if they know a good one and make the call.
Also - really - call a friend. I told NO ONE for months and months and months. I've still told only a very small handful of people, but the relief I felt when I finally confided in a few friends was PROFOUND. Friends will help save your sanity. Mine have been incredibly compassionate and understand why I'm standing (and I know will be kind to H if they see him in person). You should know who these people are in your life. Call one or two of them!
