How to behave with a girlfreiend in such situations given bellow?

In my opinion all you have to do is talk. Ask her where her head is. If she is like any woman that I have ever met in my life then she will un load alot of information. Let her tell you what is on her mind. Thats the only sure way to know what she is thinking. Ask her what would make her happy... and do it...you will never fail. Our moods, wants and needs change by the second. You'll never go wrong if she tells you what will make her happy. Tell her everything. Volunteer information to her that she might not want to know and make her feel wanted. Its sweet and honest. This is a sure way to open the lines of trust. All this talking is only beneficial (as long as you don't come off as being needy). It will bring you together even more and eliminate all confusion. Good Luck!
