Well.. she made mistake by lying and lying again to cover it. But for her to write this book, and revealing the lie she told consciously. Then she realised her mistakes and wants to correct it. And she's strong to do that. Nothing stopped her from not including the virginity part and just go on wuth her stories and maybe later claim she lost it. We won't have known. But I think she corrected her mistake to have peace and she made it open too and apologised about it too.
Girl, you were silly for lying but you're strong for owing up to that lie. That's someone repenting and trying to be honest and worthy of having integrity.
Now the society of course will bash you and judge you and ridicule you and paint you the very devil. I won't say you don't derseve it but I know you ain't a coward for this. And cause you're also a himan who is liable to fall and mess up, wear a thick skin now and know you've at least set your spirit free of lies. It's going to be rocky now but it will be steady later. Take the condemnations, don't try to defend yourself again.. just take it as ypur punishment for lying.
