Substitute

Now that you are dating a man again, I suspect that you will pull further away from me emotionally than you already have. His presence in your life will fill the void in your heart I was eager and ready to occupy. Consequently, you won't need me to answer your messages or your calls; you'll have someone else (and maybe, in your estimation, someone better) who can physically provide you attention, entertainment, support, and the rest of the services I selflessly and gladly provided you remotely. I will soon become obsolete.
