Re: are these IOIs, a little confused.
Try to kiss her. That is the best tell for you. Your guys relationship has already progressed to the point where if she wanted you to kiss her she would let you. That will give you your answer.
I see mixed signals here also. The fact that she holds your hand and touches you are definite ioi's. Also the thing about her asking if you would be upset about her talking to other dudes is a Sh1t Test.
I think she likes you to be honest, but I think she is concerned with ruining the friendship you guys have. Like I said, work to kiss close her.
There is no such thing as rejection, only feedback.
Be the flame, not the moth.
