Yeah that line would have raised the hairs on the back of my head too .... its a simple history re-write of her there ... she has justified this entire move/break and one of the reasons was she had to spoon feed and burp you for 5 years .... not what really happened right? Next time "truth Dart" her right in the forehead with ... oh .. I dunno .. something like "Really? So happy you have re-written our history because I just happen a fully functioning adult before I met you and continue to be to this very second" Then bounce right out of the room. IMHO Truth darts are best tossed in person, I never could get my sarcasm font applied correctly via text nor email.
For now .. let it go .. its just her spew crazy and you do not want any of that stuff on you!
