Thing is, I don't think anyone would begrudge her for being honest for once and saying she's not over him.
It's very apparent she's only gone through all of this as a big duck you to Oliver. Whilst Oliver doesn't seem bothered, she still seems to keen to keep proving to everyone and herself that she's over him.
5 years is a long time. Of course it's going to sting and hurt. However, posting so publicly about it and always speaking ill of her exes, (apart from AD, he deserves it) just makes you wonder if she's actually the one at fault.
Would have had more respect for her if she'd stayed single and worked on herself for at least a year or so before moving another guy in and marrying them so quickly.
It's just sad. But as people have said, she's not a nice person so what comes around, goes around
