Being avoided months later just for asking out a girl. help ?

ok ill admit, I come across as very extroverted and outgoing but maybe a bit intense. I saw a girl in the library that seemed cool and I saw her consistently show up at the same spot for a while and I decided to strike up a convo one day with her one on one. she seemed kinda nervous since I was a stranger and lost her train of thought here and there but overall was ok.

I approached her friend one day saying I wanted to ask out her friend but didnt know how to go about it and the friend told me the girl was single and was overall pretty kind and receptive. I decided to give this friend a not a couple days later basically asking her to pass it to the girl I liked and it asks her for coffee IF SHES INTO IT. THATS LITERALLY IT. I get no answer, all I get is straight up avoidance. these girls started to avoid me and I just never did anything more. I just went to my spot and studied.

the girl brought her guy friends a few days after the note and pointed me out and I felt slightly embarrassed because there was no interaction. They overall just stopped coming to the spot where we use to see each other.

Now, months after this passed, I saw an empty seat beside the girl I liked (havent seen her in months) and she was sitting with the friend I gave the note to who was right in front of her and I just sat and did my homework. 10 minutes pass and they both pack up looking at each other (I just glanced for a second by side eyeing they didnt notice) and they left abruptly. im tired of this behaviour. im scared now tbh they've already shown me to like 5-8 people and all these people avoid me when they see me (they turn the other direction). is it because im black
