Wawrinka has been relatively quiet about the incident as opposed to his wife. He said that he spilt with his wife, the matter is private, and that he has his daughters best interests at heart. Stan's ex is the only one who has given a somewhat explicit view of the situation by talking to swiss journalists. As a result, everyone is now assuming that there is only 1 side to the story, which was told completely by his ex-wife. I havent seen wawrinka give any explicit recollections about what happened between them and he also didnt claim to be a saint either.
His wife would not have felt the need to say anything had he not tweeted about it.
On a seperate note, why do people make such a big hairy deal over the baby ? Babies are resilient. She will do just fine thank you
It would have been infinitely worse growing up in an environment where the parents hate each other
Breaking up is the best thing for the child in these situations
