Since OP seems to be gone, in case she returns. I'll just say that the end of a relationship isn't the end of a person's life....even if it feels like it at first.
I was dumped with all sorts of drama and then a whimper. He left me and threw me out. Far from my family.
I was brokenhearted. I went to therapy. I read about how we choose mates. (Old, old book 'getting the love you want' by american author Harville Hendrix was a lightbulb moment. Yes. I was put off by his name but therapist insisted)
Eventually, I met my now dh. It's a healthy relationship and he treats me with kindness and respect. (I also made a list of traits that i wanted and he met all but one; he's introverted, a bit shy, but it's endearing now).
My ex? Married the woman he dumped me for. They had a ds. I looked ex up a few years ago on sm and his dw looked unhappy. Last time I looked, she was remarried ...and grinning from ear to ear, she was glowing with happiness.
Ex as still writing sad songs. Alone.
My long-winded point? It's on you to grieve, learn, improve your self understanding, be who you want to be instead of a person who will please your dp. You'll heal. You'll survive and potentially flourish.
And like both myself and the woman that I was dumped for; hopefully you'll find a person who enjoys you for yourself, loves you as you ought to be loved and will be a partner who isn't a disrespectful, selfish turd.
This is for OP, or anyone whose heart is broken. Being dumped was the best thing that ever happened to me. Embrace this as an opportunity.
