Unrequited love can be one of the most painful experiences in life. It can make you feel like your heart is breaking, especially if you have been with that person for a long time, invested your emotions and time, and even sacrificed some relationships for them. But what if that person changes and doesn't love you back, or doesn't want you in their life? How do you move on from someone who doesn't value you?
The first thing you need to do is to remember who you are. Remember who you were before you met them, what you wanted, what your dreams and aspirations were. Have you been happier or sadder since you met them? Have you changed your likes and dislikes to please them? The truth is, you don't have to force yourself into someone's life. If you feel like it's a one-sided relationship, take a step back. It may be hard, but it may be the only way to heal.
The next thing you need to do is to be selfish with your time. Spend it on yourself, on your hobbies, on your friends, on your goals. See if that bothers them. If they don't show any regret or effort, then you know they don't care about you. Maybe you need them more than they need you. But you don't have to. You can love yourself enough to not need another person's love to feel complete. You are enough.
The last thing you need to do is to let go of the past. Don't dwell on what could have been, what went wrong, or what you could have done differently. The past is gone, and you can't change it. What you can do is to learn from it, and use it to grow as a person. You can also be grateful for the good memories, the lessons, and the experiences that you shared with that person. They were part of your journey, but they are not your destination. You have a future ahead of you, and you deserve to be happy.
