I really like this shy girl but she kinda ignores/avoids me. Her best friend told me this girl liked me so I don't get why she is doing that?

I have a problem with one of my female friends (i'm a guy).

I've been crushing on her really hard and I think about her pretty much all the time. She does know I like her as far as I know. I asked her best friend once and she said i'm the kind of guy she likes but the thing is she ignores/avoids me most of the time.

Every time when we're in a group (mostly 2-3 guys, her, and her best friend) she acts like i don't exist. She's very shy and passive and I've read some articles cause I was curious as to what girls do if they like a guy. They say that a girl who likes a guy stands near him, looks at him etc. But she never walks beside me or looks at me. As a matter of fact she has no problem communicating and maintaining eye contact with my male friends. Do shy girls show other signs of interest or does she not like me at all.
I get along extremely well with her best friend and I can talk to her a lot but I just can't get a conversation like this with my crush...

What baffles me is that she is very open as far as texting is concerned. Even though I have to initiate EVERY single text (I hope it's because she is very shy and passive) she always answers and keeps the conversation going. We're even at the point where we give each other cute nicknames.

Therefore I don't get this girl since she is comfortable with texting me but ignores me in person. She does laugh at pretty much all my jokes but that might be cause I'm a funny guy. I compliment her a lot, only when I really mean it though. In texts she always thanks me followed by a blushing face but when I compliment her in person she kinda brushes it off and doesn't thank me.

Has anyone experienced something like this?
