Nexus,
I'm new to this myself but will try and help out;
firstly chase wrote an article about this which you can read here:
https://www.girlschase.com/content/how-a ... ys-get-yes
Its a good article and the important thing to take away is keep things simple, like you i used to think you needed magical words to ask a girl out but you really don't just keep it simple and ask her, if she's interested she'll say yes. I normally just say:
if your free sometime this weekend we can get a drink/coffee/ice cream (pick the one you prefer at the time)
Here is an example of how i asked a girl out last week. Like you I met her in a club the next day we got chatting on facebook and we got talking about my love for ice cream eventually i framed her as someone who wanted to try and steal it which she brought into saying she would ask for some, I then asked her out like this:
If your free sometime this weekend we could meet and I'll give you some
in less then 1 minute she replied yes. Btw i didn't plan the whole ice cream thing I just saw an opportunity and took it.
Just out of interest is this the nurse you asked about a couple of days ago? Because you said she seemed interested and said she was free the next week, if that's the case read the article and ask her out asap.
Ps if some parts of this don't make sense accept my apologies i wrote this on my mobile phone whilst working a night shift.
