Most Helpful Guy
Did he talk to you about this in person? Because if so, what kind of emotion was he giving off which would be a give away to if he was making excuses. And shy guys would usually be ones to be scared, so if he is really an out there guy, I highly doubt this is true. Otherwise I'd believe what he is saying, and don't push, but gradually go back in. If it could have been really great between you, then it should shine once he is his feelings are in shape.

They were together for Five long years and with a bad break up, I feel he is telling you the Tough luck truth of Not wanting to jump right back into the fire so fast with being hooked at the hip. I also feel that being he said what he said to you, he was this Honest John in telling you 'The only girl who made him think again of having another relationship but he's so confused...'
You both really needed to take this slow with the flow, go easy and begin your beguine by nursing and nurturing your Friendship First. You knew what you were up against with a heart broken man and this should have been handled with kid gloves.
Breaking it off really wasn't the answer unless you expected Rome to be built in a day with a rolling romance. Life is no guarantee of course, for who really knows what would have become of your saga but starting off in a Friendship was the Best place to have started with no strings attached...
No, not 'Making excuses' but I think you may have found a few of your own by wanting something faster than he could provide for you. Maybe you could give him a call and ask how he is? No harm in being friendly, he has done nothing wrong and yes, definitely he is 'Heartbroken and scared' and Now---Is perhaps a bit sad in losing out again another battle so fast.
Good luck. xx
