That's what you don't get. When you DB, you're trying different things to see what works. Even a negative reaction is good. You learn about it and file it away. Even when she says something negative, you make a note of it and file it away and then continue to enjoy yourself with her. When you talk about something that gets a negative reaction, maybe try to approach the subject in a different way with different words. There's always something to learn even when it's negative.
Good point, I am learning what's a negative and obviously taking steps to not repeat them. I would just like too see her smile towards me a couple of times or say thankyou etc. I'll keep DBing, things aren't getting worse so I guess that's a good sign
