Would you be willing to continue on as you two have been (and you not say anything to him at ALL about committing to you), meanwhile giving him another six months to do what he thinks he has to do. After that, if he won't commit, you walk away.
(Will you come back and let us know what happens? Pretty please?)
Definitely!! I am now praying for strength to be able to not bug him (LOL). He is a very good person so that's why I am really trying to see this thing through.
