i had the same problem with my dp, he just didn't feel ready.... get your friend to sit down with him and talk about exactly why hes not ready and what his concerns are. have her reasure him about things he is worried about... worked for me... of course it does make a difference what he is worried about or why he dosn't think he is ready but maybe if she can calmly reasure him and explain why she wants it so much and how confident she is in the process, this is what worked for me
