I feel like a pick me

I arrived three weeks after classes started and had trouble fitting in
There aren't many girls at my university, and in my class most of the girls come from the same school ( I don't)
every time I approached girls ,they acted like I was a bother (they won't answer me they will just look at each other in silence and wait for me to leave before talking again)
So I was alone until this group of boys started talking to me , and I didn't even expect myself to be able to fit in with them that well.
But recently things became weird cause I got 2 different anonymous confessions ( I thought it was some kind of joke between us)
But one of these people came to me in private to say that he was serious (because some people saw him writing it ,so everyone it the class knew) he sais that he didn't write the second one. No one asked me out they just said how they feel around me.
I just said thank but somehow it feel weird to still stay with these boys even more I started paying attention to how they looked at me
Idk how to even explain the vibe in that group Nobody claimed the 2nd confessions
