<human>: I can't remember how we got on the subject but I told her she was a 9/10 (referring to her looks). Knowing my own scale, I consider a 9 to be a big compliment. I rate hot celebrities like Rachel Bilson 9. A 9 is amazing. Damn near any guy would love for their girlfriend to be a 9. This is not how she took it. She instantly wanted to know why she wasn't a 10. When I stalled she asked me who was a 10. I blurt out Emily Ratajowski without thinking. An endless number of questions followed, none of which had a possible correct answer. So now she thinks her boobs aren't big enough, she needs to lose weight, and wear makeup. I don't think she needs to do any of that. In fact her boobs are amazing, she is the perfect weight, and I don't even like girls who wear makeup.  Doesn't matter, she doesn't believe me.

The worst part is I really do think she is perfect for me. I wouldn't change a thing about her. But now I'm "the reason girls have complexes". I guess I'm just a little too honest sometimes.

Can you summarize the given text in a few sentences?
<bot>: Don't ever rate your girlfriend. Don't even rate her a 10. In fact, avoid discussing her looks altogether.
