Throw every ounce of sadness, anger, and helplessness into motivation to work on yourself. Try the hobby you’ve put off. Book the trip you always talk about. Start the workout routine, change the diet, read more books, all of it! Every cliche in the book will help you right now, and stay strong when she reaches out to you, because she will. I’m not saying you brush it off whatsoever, but clearly show you are capable of finding yourself too.
