How to get over your ex when he's your best friend?

hey i dont know how else to contact you so im just going to write on this thanks for your opion, its pretty spot on, thats why like before either of us said anyhting we had litteraly never faught.. then in the past month we have faught quite a bit never anything big becuase its just not us, and i end up feeling extremely bad as i know this is the last thing she wants to be worried about, she is amazingly strong and a big inspiration in the way shes been handling this, we've spoken about when this happens how she wants me with her, wnats me at the funeral and im completely fine with that, i just hope it brings us closer rather than making us more distant, shes litteraly the most inportant thing in my life, and i just want whats best for both of us, i just cant help buht wonder wether we will ever happen though:/
