best friend delema..

My best friend is preg. with her first child and im really excited for her. She is making me the god mother and everything.. but since the bitrth father wants nothing to do with her or the baby(mainly bc he’s a dead beat) she has been looking high and low for “love” and she’s the type of girl who will listen to what ever youtell.. im really concerned bc the guy she is with now isnt her type at all.. and I can tell he’s playin games with her head.. hes only telling her what she wants to hear.. and nothing out of his mouth is sincere.. his X girlfriend’s email me all the time saying that he wants them back adn that my bff means nothign to him.. I’ve seen the text from his cell to theirs.. and the emails.. I’ve showed her but she doesnt want to believe it.. she says hes the best guy to have ever walked into her life.. but seriously I dont know what to do or say to make her realize hes not the one for her.. is it even my place? am I over stepping my boundaries as her best friend?
