Our text messages have gone as follows...

Me: it was nice to see you, and we will do it again sometime, since I have your number.

Her: that would be great. My sister is having a small get together for her birthday at dinner. But yes we should hangout soon.

Me: I have to cover night shift this week or I would be there.

Her: be safe out there ya damn owl.

After just seen her on Saturday I know the rule of thumb is not to see her more than once a week and keep texting to a minimum. How can I keep myself in the driver seat before things get out of hand?
