I know how you feel. I was married for 24 years. My divorce will be final this month. I am STILL longing for my ex. He has moved on. I cannot. I have tried but I cannot. I wish I could offer some great words of wisdom or more importantly, solace. Time….time…time……this is the only healer that I know to be the real deal. Grieve and learn from it. Big hugs to you…….and always know that “this too shall pass”
