just be yourself and if that doesn't work she\he is not the one for you, or try to get the persons attention by staring at them or giving them a little smile once in a while ;)
Maybe she is feeling a bit insecure at the moment. Some girls might feel like this if you are not paying her much attention. Spend more quality time together as a couple.
I believe that 'you had been asked' sounds correctly and the other, has the wrong tense. It has been set in present tense and is not used as often; therefor it will not sound correct to most people.
