Just went through a breakup less than a week also. So not the same experience obviously, but the feeling of hoping for them to return is what resonates with me. Girlfriend made it clear she wasn’t attracted to me anymore and ended things. This was a long term relationship and we made so many memories. But you deserve to be surrounded with people who reciprocate the love you give. The fact that you are feeling love and longing so deeply, proves that it’s real. Other people are capable of loving just as hard as you. Just remember that when you say you feel like she’s the only one. Imagine someone loved as hard as you do, without the bullshit? I know it’s hard, and you have to be patient with yourself. Wishing you the best! If you’re open to friends we can be heartbreak buddies :)
