Search Results: she needed time to find herself

The reason I ask is because I've had feelings for a girl for quite a while, she has a boyfriend which is an obvious no-no, and I wouldn't do anything to cause them to break up, however I do care about her, and I want to remain her friend, I don't really care about being frendzoned or not at this point, since we get along great.

I am surprised though how oblivious she is, she's never giving me hints or even suspected that I might like her, however in the past I have felt like some of my actions have been obvious but without being too direct. For instance when I see her, my voice goes really deep, I smile a lot when I see her, and I can get really awkward.
We often email/text back and forth a few times a week too, and I sometimes playfully tease and joke about with her.

I also often make her feel good about herself since she is not very confident, and I always try to perk her up if she feels down. I've also told her that I'm there for her, if she ever needs a chat about anything. She often tells me quite a bit about herself whether it be good or bad, and vice-versa. She has done some flirty things to me too recently such as touching my hair, my hand, making references to hanging out. I find this strange since she never is like that towards other guys.

So anyway, do you Girls/Women have a rough idea whether guy likes you/has feelings for you or not?
