<human>: Can you give me the gist of the text in a nutshell?

I'm going NC with my ex of 3.5 years. We haven't contacted each other in a few weeks but before I cut off all contact I found out she was already dating another guy. 

She broke it off with me because "she didn't want better, but something different."

NC has done wonders for me so far (I'm still hurting but I can see the light at the end of the tunnel), but theres a nagging question that keeps popping up in my head day after day. 
I want to know if rebounds postpone the pain of the breakup for women? Is the saying "I'll hurt today, they'll hurt tomorrow" accurate?
I've never rebounded after a breakup, I let all the pain hit me and hard at the start, because if I'm going through hell I want to get the hottest part over with.
<bot>: Ex broke it off with me, started dating new guy very soon after. Ladies, will this postpone her pain or is she feeling pain like me?
