<human>: Can you provide a brief overview of the text?

So that's pretty much it. She wants me to listen to her problems over and over and sympathize. For example she has to work for a month at summer. She texts me every day how she is tired of it or how she has some health issues, or how she's fat although she's really not.
Yesterday I said that I have some issues too but I simply don't expose them to her. She wanted to know about my problems. I told her and asked "What now? What can you do about my problems? Nothing. As nothing can do I about yours. I can just sympathize but not all the time about the same one problem." She said she understood everything, cried and went to sleep. The whole dialog took place in facebook.

So I need to know is it me the bad guy for telling her instead of cheering her up or what. I don't actually know what I need to do in such moments: tell the harsh truth or sweet lie.
We've been together for 9 months. It's my second relationship, her first.
<bot>: I got tired of sympathizing her over the same problems every day and told her about it only for her to cry.
