I understand how you feel, but it seems to me that you don't quite understand how girls feel and think. My ex-gf was doing the same like your gf. I always thought that she was 小气小心眼野蛮不识大体疑心重, 时常怀疑我去找别的女人. well, girls thought so because they loved their bfs and didn't want to lose their bfs. Even the toughest and strongest woman will become soft and dependent to her lover. They want to share their feelings and thoughts with their lovers. If they don't care anymore, they don't talk. My gf is 24 years old and has a Master Degree. However, she acts like a little girl in front of me all the time. You feel bored with her because you have been thinking she is not the type of gf you want. I think you should re-consider. Her bad sides that you see today could be her good sides.
