1. do you dare to approach the guy that u like?
2. will you tell him that u like him and want to be friend with him? how? pls share and give me some ideas...

Dont direct tell him u like him, use some tactic like ask the guy hp no., go shopping or go pub (no disco-noisy). Call him frequentyly by a week, but next week dont call him. Let see what his re-action. I think u will more clear after this.

This is my present gf (obbbbbbbb wife already lah) used it, she use this tactic to me, after 2 or 3 weeks i can hold the icih mind then call her & tell her i hv a fell with her.

3. do you ever think that you are not suitable for the guy? i mean u look down on yourself, think that the guy is so great that you are not the right one for him...
No, never ever think that. U will find your value in future.

So, i can say dont stright away, hv to play some tactic 1st. Atleast u can fell whether his got fell with u or not.
