can you like someone you've never met or spoken to?

[Olivia]

there's this girl who is a friend of a friend (that i haven't seen since high school so i guess acquaintance) and i've never met her before but i always see pictures that he puts of her on social media and there's just something about her that makes me feel a certain way. like i want to meet her so bad, i don't know if i just want to kiss her and be with her or if i just really admire her and want to be like her?? does that make sense? i've never ever felt this way about anyone.
i have a boyfriend that i've been with for a year now. and i've had crushes on other girls before but this is different.
can anyone explain why i feel this way?
