Search Results: attracted to outgoing women

So I've been reading up a lot on body language and signs of attraction and I've been trying to get better at noticing when a woman is attracted to me.

"Amanda" introduced herself to me when we first met within the first couple minutes I arrived and she teased me playfully. She has done similar things the last 3 times we saw each other. She always makes sure to say hi to me so that I notice her, but the other women in the group do not (except the other one that I know is interested). I don't doubt there are other guys she says hi to, but not all other guys and I am the only new guy and I think the only guy who is older than her.

This past evening was the first time I had a chance to observe her behavior because we were all in an apartment. During the evening I was talking to some guys and another lady I know has interest in me came over, and then within maybe 20 seconds "Amanda" walks over and joins the conversation as well. I suddenly became the topic of conversation about some silly "skill" that I have, and "Amanda" joked that I need to practice and show her again next time she see's me.

Near the end of the night I saw her talking with another guy, however her arms were crossed. As she was leaving I made sure to say goodbye and playfully tease her a bit. She uncrossed her arms, and her pupils were dilated significantly for the first maybe 30 seconds we were talking, then they returned to their normal size.

I've been reading up on body language and attraction signs and I think it is likely that she's interested, but I'm still new and not quite sure. She is definitely a very outgoing person, so that's what makes me uncertian if she is attracted or just being friendly.

I'm definitely going to ask her out regardless, but I want to develop my body language reading skills too. Would you say she's interested? Why or why not?

Thanks!
