Turbo, good on you for giving her the time of day.
If you do take her out, my best advice is to be completely honest with her at all times. No game playing and no leaving her hanging if you're unsure. If there are issues eg; she's texting you a lot, set the parameters as to what is acceptable to you. But be very clear - leave nothing open to interpretation. Instead of saying "Don't text me so much" say "four texts per day is good" or "I can't text when I'm at work, but the evenings are good. But not on Tuesday nights because I play tennis"
And I'd also suggest you get to know her mother very early on and show that you mean no harm.
Never regret anything that has happened in your life. It cannot be changed, forgotten or undone. So, take it as a lesson learned and move on.
