The key point I was trying to make with the once a week thing, is that you should try and get it so it's her initiating the conversations - women prefer it that way afterall. I'm not saying to purposely be a cold dick or anything, but a guy should have far too much going on to be texting a girl day in day out
Also, I like to build attraction in person, and leave her in a position where the only reason she'd text me.. is because of how much she wants to see me again. So "When are you free to get together?" would be a good thing
if you're interesting enough in person, it doesn't really matter that you like to get straight to the point when texting (though it was primarily for the early stages)
Thanks for the feedback
