Hi icetea,
Well it seems he does have some unresolved issues, and unless he works through them I don’t think he is ready for a relationship yet. Also, i don’t think that either reassuring him or scaring him would be the solution as the cause seems to be in him. He needs to be sure of what it is he wants deep down and what he is afraid of etc. Otherwise, no amount of external reassurance would ‘compensate’. From what you wrote, he doesn’t seem sure himself on this point. Again from what you are saying, it appears that if things continue as they stand, you might get (even more) hurt seeing he is constantly vacillating and is so unsure of his emotions. There's just too much baggage atm...
