Why would a girl act so different in a group and when am alone?

[Luvme66]

Sadly can't give check the physical vibes... Cause we are gaming friends...
So when me and her are alone playing... when no third person is around... she acts cutish... but when we are in a group.. she is a bit less engaging. Umm I don't wanna know if she likes me or not... I just wanna know what goes on in a girls head?

She either shy or don't like to be in the presence of you or anyone

[Luvme66]

She ain't shy though

[Alicealex]

Sounds shy or just overwhelmed. Does she know the people or feel comfortable with them?

[Luvme66]

Yes she does know them and am sobsure she ain't shy..
