So I meet a girl at a party who I find attractive. I talk to her (for the first time) and things go well. I end up talking to her until she leaves and we say goodbyes. A friend of hers approaches me and tells me that she found me attractive. From judging body language when I was speaking to her, I could see the signs of attraction, I just couldn't grasp how interested she really was.

Anyway.. I ended up getting her snapchat from her friend, she added me back. How do I proceed?

Currently have two options

A. Wait to see her again irl (roughly a week)

B. Snapchat her and proceed from there, if this is the better option, what would be a good opener rather than "hey".

Thanks in advance for the help gents
