If you got the number, that means she's open to getting to know you. So, as others are saying, just call and ask her out to coffee or drinks or something casual at first so you have a chance to talk a bit and get to know each other. You'll be fine! =)
Don't ask for phone numbers and dates like you're trying to score a touchdown. Instead look for mutual attraction and interest--you'll feel it, you'll know. Then when she gives you her number, it will be the real deal. Of course she will say yes when you call.
so, it has been two weeks, how did it work out?
u can txt but its better to Call and ask "nicely" lol
If you've got their number, then you've also got the date. All you have to do is make it happen by dialling the number. She will be grinning from ear to ear and thrilled to death, so don't worry about your mojo; just make her day and ask.
