(I'm 22 and in college)

So, a couple girls came to my house on Friday and brought a friend who I never met before. She was quieter than her friends so I decided to talk to her. We shot the shit throughout the night and as her and her friends were getting ready to leave, I said "hey, could I get your number? you're pretty cool to talk to"

She sort of chuckled and said sure.

She friend requested me yesterday, I accepted, and then wake up today with a message from her telling me that she may have given me the wrong number the other night.

IMO this is a good sign because she cares whether or not I have the right now.

Now for my question. I'm a pretty avid texter. I'm one of those guys that tries to build attraction via text. But I'm going to stop that now... I want to ask this girl to hang out. Do you think I should ask her to come over tonight alone? With her friends? Or wait til a random day during the week?
