Re: She always answers but in a laconic way
I second what t-mal is saying.
I do just want to add that since you're probably looking to have her invest more it might be reasonable to invest more with challenging statements, questions or scenarios. Continue to stoke the fire with more wood. Another tip is to think about what you're saying or asking--if its a complex and indepth question thats the kind of answer / response you get in relation. Avoid yes / no or one word answers and responses unless its needed to move forward in the relationship
Every moment counts, get out of your head and enjoy it.
