He is telling you that 'Now' is Not a good time but maybe down the love line in the future. However, that could be something he is just saying to keep you swaying in the wind if he doesn't bother calling or even puts you on his Pay no mind list of Not paying you any mind.
If he does come around, keep it light and semi sweet and just go easy with Nursing and Nurturing a Nice Friendship again even if it comes down to This. Getting to know One another will help in possibly getting back together but if Not, focus on You and let him stay to the side until he might Decide... What he really wants so you do not become just A... Side.
Good luck. xx
