You need to have faith in her. You need to stop assuming you are doing things wrongly, you need to trust her ability to notify you if you are doing something wrong. In other words, if you are doing something wrong, trust her she will tell you.

We all have moods, if she isn't talkative, try asking her if anything is wrong. If she replies no, respect her wishes and try making the experience fun, try having her smile, if it is important she will tell you what's up.

Let her know you are trying to change these factors, but she is going to need to help you along the way, she needs to be both sincerely open and truthful with you, if there is something up she needs to be the one mature enough to bring it up and not let it linger.

You two need to work together. =]
