About this guy...

I was at work one day on break and talking to one of my co-workers , he was basically setting me off with a guy who had a same personality . And he keep saying names until he said this one name we are going to call him Tim (for privacy reason ) and I was telling my friend that Tim doesn't likes me, because of my past or maybe because he only likes white girls (Tim is black ) . So my friend was saying Tim is not like that I know him personally, I'll talk to him for you . Then fast forward a week later my friend came in to buy food, and I was in my break and I ask him did he talked to Tim . And he gave me the look and in my head I was like "I knew it he doesn't like me . And my friend said " well time came over to my house to drop something off and I told him about you , and he was smiling and Tim said " why didn't she never tell me , she never gave any sign or anything" and Tim told my friend tell her to come up to me and say Hey

And in my mind I was very surprise with Tim's response . Because when I see him the hallways in school he is very expressionless .

Monday: I was getting cute and feeling confident to talk to Tim . But I didn't see him that day maybe he was absent

Tuesday: I saw Tim , when we're switching class and he look at me and I look at him. And my body froze up and I turned my head the other direction

Today: I saw Tim we were having an assembly and I walked passed him and in the corner of my eyes I saw him talking to his friend when I walked passed him. And I saw him again during class in the hallways on his phone and I put my headphones on and pretending not to see him

In general I'm just so nervous to talk to him because we never talked before he knows of me and I know of him . And I feel like I'm not his type because he hangs out around with non-black girls who are very attractive . And I'm like what's the point he is a senior and I'm a junior and he is going to be leaving soon. I feel like it's too late.

Ps sorry for the long post any advices?
