I understand that at this moment you are finding it hard to move on as the experience is still raw for you. Take a moment to mourn the loss of this relationship and do your best to forge ahead by yourself. Trust me it will take time but I know you will get through this.
My first serious bf after our break up, i had similar thoughts like you. it took me a year to move on, so if I can do it so can you.
Good luck!
