If you like very much somebody, how you will show your love or atraction?

there's this guy who always tells me to trust him that he loves me but i have this fear of being hurt again because of loving the wrong person, he is doing everything that he can to be able to show me he's really interested but i just can't give my trust, it's because of fear.. maybe it depends on who the person is and what he/she really is feeling about you and what yoy show.. if you're really interseted in him/her, show it by doing everything you can to let her know you're true feelings.. ^^,

That's not really something that you can convice them about, your actions have to speak for your feelings. It's not sure that who you like likes you back, try and ask him / her about it indirectly.
