i think it's better to hint the guy rather than approach him directly...
normally if u give out hint for few times the guy wil realize it... if he din do anything it might bcoz he dun love u, that's y he jz act like nth happen b4...
giving up after that is quite gd bcoz u ady did wat u can, n yet nth changes... wat u can do is give up only, if not wat else u wanna do..? those kinda so called scary ppl wil do whateva to get a person they want, but think from another angle, if u give up n leave with ur "zhun yan" is always better lo...
that's what i think la...at least u'll leave dat guy a nice image...^^
