OK, been taking a dancing class for a dozen weeks, at this point had little chatter with this girl one girl in particulare. My friend befriended most people at the dance classes, but I didn’t pursue any possible friendships. At the final lesson kind of a big thing this girl and I chatted more and more, eventually danced with here for awhile, and went outside to get air, I got her number and semi liked her at this point. She is really cool, we hit it off.

This is where it gets complicated. Her brother is kind of my enemy. So naturally I was reluctant to peruse her. My friend started texting her as he got her number, but I felt I left it too late and didn’t end up talking to her.

Recently my friend has meet up with her and I am super jealous and kind of angry at him. I just need to know what if anything I should do/ can do. It’s been over month so I don’t know if I should contact her. I can’t believe I don’t peruse these possible friends in general, kind of down about it.

Did she dance with me to get my friends attention back?
Can I still start talking to her?

Okay, I'm a woman and I don't understand the whole dancing w you to gain your friend's attention. That would only make sense if she was completely imature. I don't see why you can't talk to her. Invite her over in a group setting and begin a friendship before you go all for a relationship- after all, are you trying to find your future spouse, or a break-up? If neither of you are in it for life, then obviously, you will break up and someone will end up hurt. Don't pursue a relationship with her until you're good friend's first. Generally speaking, girls (or women depending on her age) like to know a guy as a friend first, so they can actually TRUST him and have a foundation when the mushy drama of a relationship comes into play. But yeah, ask her if she wants to hangout w you and some friends, what's the worst that can happen, she'll say "no?" if she does then try again another time- just don't give off a stalker vibe, be sincere in your invitations and respect any other friendships or relationships she may already have. That's my advice. I'm not an expert, but that's all I got to say.
