What should you do if the man you like keeps flirting with you and makes eye contact but he keeps running away from you?

it sounds unusual but men are afraid of rejection,, they are very sensitive, that's y they are such manly men, "you can't hurt me so don't even try" there are a number of reasons y he wont engage. he might be a player, not wanting to use and abuse you. he could like you alot and afraid that if he made a move that you would react negativly. and it could just be fun flirting with you, he might just like the attention, but doesnt want to take the next step
