<human>: Can you condense the text into three sentences or less?

Me [19/m] her [19/f]
We have only been dating for 3 months now but I feel something might be off in our relationship. We are in a bit of a long distance right now , we see each other for about 2 weekends a month but that is going to change in about 2 months and I will see her everyday (school will start).
We text/skype everyday and I feel she is always demanding my attention and wants me to work and make the relationship more "fun". She expects me to flit and be funny all the time, but I feel she is not putting any work in the relationship .She is just waiting for me to do everything. When we are talking she is acting like a spoiled child that doesent get what she wants, doesnt say she is mad just gets all bitchy and almost ignores me. 
While we are together things are great, no major arguments, always having fun, we are probably still in the honey moon phase.
Should I mention to her that she needs to put some effort in the relationship? what would be the best approach?
<bot>: GF wants me to put effort in the relationship, she doesn't  do anything about it. What should I do.
