I'm not seeing low investment here at all. I think you are investing a bit much. The juices flowing line is great, but just leave it at that. Don't add multiple questions to texts or start two separate discussion threads. Your game looks good brotha, for a science nerd you've got moves ;). I might say "Don't worry, I'll hold the door, pay for your drink, pull your hair... all like a perfect gentleman"

honestly not a big fan of the last text that you sent, you dont want to say that your going to be a perfect gentleman unless with extreme sarcasm, another problem is you sorta assumed the frame that you "owe her" and shes playing into it. "so bossy"
