I would totally save his messages and show them to my friend: she can get professional help later after that because, as Aeriandra said, that piece of crap will, for sure, cheat and abandon her even if there are kids in the middle. It will sound cruel but if the result is, technically, going to be the same then it's better to do it while she's still young and with less responsibilities..... No, scratch that: if there were children it would be way worse since the load on Hari's friend will be heavier...
And thanks for the translation!
