<human>: Can you give me the gist of the text in a nutshell?

So, here's my story. I'm in a 15months relationship with this girl, we're both 21yrsold. Everything is fine, we have some arguments time to time, but I think that's usual for a couple, huh.

So, she told me about this issue she's having with my behavior, saying that I'm a coward, I don't do things because I'm afraid etc etc.
Partially it's true. Partially it's just because I'm lazy as fuck and I can't get my ass off my chair, when I'm at the computer. So, in the middle of random talking she told me she's been posting in an online forum (not reddit, language specific and not even english) about a friend of hers and some problems with fitness and shit. She said she didn't want me to read what she's been posting, so she didn't give any detail on which forum, which username she was using. With some research and googling, I'm 100% sure I've found her. One of her posts says I'm a coward, a childish teenager who's not even close to an adult, and she doesn't know if she loves me anymore (we just had sex, and that baffled me completely.). According to what she wrote, I'm 100% dependant on my parents cash and care, I'm a spoiled child with some arrogant behavior and no real purpose for my life. To make things clear, I live in middle-high class family, and she lives in middle-low class family. Reading that and all the shit she threw at me, made me think, and I wanted to come here for advice.

So, I'm here, not knowing what to do, if I really want to be with her too, cause that read struck me deep in my feelings. She said, also, that I'm really perfect on other aspects (which is true, I'm patient and comprehensive, but I don't really care...) but she still doubts about her feelings for me.

What should I do, reddit? Shall I talk to her, saying that I found what she wrote?
<bot>: GF writes on the internet that I'm a spoiled douchebag kid, but still acts like nothing is wrong with me. Don't know how I can handle that.
