Please HELP!Why does she do this? Whats the deal here its an intersesting story please read real quick?

okay to be honest i think you lost her kid...i mean she moved on..but that should be a lesson to you next time you're into someone respect them and treat them how you would like to be treated and maybe they'll stay.. but see it's karma she's making you feel the way you probably made her feel: like ****=) good luck though and next time change before it's to late..
