Sweetheart, you have asked for stories with happy endings, but you are so not ready to hear them yet. You are hurting, and you need, like an animal, to be somewhere safe, and to lick your wounds. You need to heal, and even then actually, listening to other people's stories of how they met their Mr Right is still probably not going to cheer you up, as you will need to find your own happiness.
Give yourself time to hurt. You need to mourn what you have lost - though it sounds as if you are mourning the loss of what he offered, rather than that particular person. But be sad for a week, a month, a year. And then stop being sad and find what makes you happy.
IME most people do find someone. But those who are happiest work out first what is important to them. If having children is the most important thing, you can do that, and then look for a man. If being happy is the most important thing, then try lots of different options.
IME, changing jobs was hugely useful as part of a fresh start. Getting a new job can mean moving area, or just buying new clothes and being with different people each day - a great way to start to move on. You can then take up new hobbies, reconnect with old ones, find new skills, or whatever. But heal first. Don't expect to find happiness whilst you are still feeling sad . . .
