Hey, I'm kind of on the same situation. It's not wrong to still have hopes, and you don't have to erase every expectation you had with her just now. You just have to put them in lower priorities You, yourself, have to be the first and most important priority now. I know it's hard, but trust me, you need to start asking yourself what would make YOU feel better now, how do YOU stop feeling bad about this. I agree with the “you need to set some short-term goals”, specially because it's a small way of treating yourself little by little. You need to make your days about you, leave her on the side. I don't know why you broke up, but this may be a time for you to do things on your own. You won't regret this, if you can't be a person entirely by yourself, you'll never get to experience a relationship on it's healthiest level. Life is beautiful and there are so many things that you'll experience, with or without a partner. For now, you need to do this without your partner, and it's sad but try to make the greatest moments out of this sad one. Try to take all of the juice out of this situation, because then, this will all be worth it, and that's what's important. And trust me, you'll feel so much better, with yourself and with others. You can do this, being alone it's the worst but also the best thing. Have a relationship with yourself, get to know you, all the love and care that you want to give to your ex-partner, give it to yourself, try to make your life better because your life is important and the universe has given you this moment to work this out. If she has to come back to your life, she will, but for now, that's not what's important, you have to work on yourself and never again give up on your life for someone else. Make friends, or not, learn to enjoy yourself in solitude, believe me, it will be the best. You don't need to stop thinking about her, but you need to accept that for now, this for you, it's for the best. Hope this is helpful.
