This is a comment I posted on ASKFDS in response to a fellow Queen who found out her ex is dating someone new:

That person he’s dating is not important to your life and neither is he.

You have been able to make it on your own without him and I trust you will keep on doing so. The relationship you had with him is gone. One hundred fifty percent gone. It has been done and over with for a while now.

Listen sis, people rarely change. It’s not “you weren’t good enough for him” or “you’re less than anybody”; it’s he found a girl who is willing to tolerate his bullshit. No, you were not too weak or sensitive -you’re normal. Get it through your head. There’s nothing special about a girl who chooses to tolerate awful behavior; she would just be a doormat. And you’re better than that.

Don’t look back sis, because you have every right to ask for a respectful, healthy relationship. After all, you were clearly not getting it.

Edited to make it more general. Hope it helps y’all.
