How do you tell a guy that you like him? Without sounding eerie/weird. Without saying I love you. Without sounding too upfront? I met this guy when I went on a vacation he's far away from me now. But we still write to each other. He had already told me that he likes me and that he has been thinking about me but I didn't reply or I didn't talk about it for a while cause I was shy and I didn't know what to say! Now I do know what to say and that is "I like him too" but it I'm finding it too hard to write them in this damned greeting card without sounding how I do not want to sound like. To make it short: I need to tell him how I feel without freaking him out! Heeeeeeeeeeeeeeeeellllllllllllllllppppppppppp!!!!
