I'm not sure if anyone can help you with dreams and goal setting, but maybe you can start with the things you had to compromise on for your H? For example my H would never contemplate adoption or fostering but now that I am planning for a possible future without him I can dream about fostering as soon as my kids leave home. I will also study more and decorate the house the way I want. I'm not dreaming of another love, but that's just me. I don't see how that could work for me, so I'll pass for now.
