I got talking to a girl from my university, and suggested we did some work later tonight, she said she was going to just have a rest and so I suggested that I'm back in town Sunday, and hence we should do some next week. She misheard me and said she's got something on Sunday, however upon realising her mistake, gave me her number and said she would get her friends together to do some work with us.

I obviously, just want to take her for a coffee etc. I work perfectly fine on my own. I have her number, (got it a few hours ago) when should I text her and hence give her mine? I usually do it straight after (maybe an hour later) so they haven't time to doubt your personality etc.

Other then seeming a bit busy etc, she did show IOI's i.e. asking me questions when the conversation naturally lulled.

Any advice on how I could turn this more into a date scenario / and also specifically when and what to text her would be much appreciated.

I'm aiming to get two girls numbers a week at uni in order to get used to it, and just generally enjoy meeting people.

I'd start by omitting the word 'hence' from your vocabulary.

Nothing wrong with texting right now - write "Hi, it's X. Is this the number for the penis reduction clinic? "

Banter a bit, suggest a coffee (or a beer) and get a time and date out of her before letting her go.
