Re: Texting a girl who I have not seen in years.
When a woman calls you darling, that is a really big deal but you seem to have blown it with a very bland reply, instead of something that gets her juices flowing.
With the benefit of hindsight, always a wonderful thing (Lol) you could have responded with something a little more Flirty, to let her know your nerdy days are behind you.
Women really love it, when you are direct and when you get more experienced you will know how to push her buttons and get her attention.
You could have said something better like
'Hey Babe long time no see I'm taking you out, lets hook up for a Coffee and play Catch up'
If it were me, I'd have ramped it up even higher by adding something like 'Then you can tell me all about the trouble that you have been causing while I've been away'
But only you know her well enough to know how far you can go, without offending her in any way.
Though women love to be perceived as being a bit naughty.
The Power in a Relationship always goes to the one who cares the least
