<human>: We've been dating for 3.5 Months. She has a child that is 9 weeks old and I knew she was pregnant (obviously) when we started dating. I was having an amazing night with my GF, and there was a tall woman with huge boobs that were right at her eye level. We kept walking and she brings up that the woman's boobs were at her eye level. I know that my GF gets hurt anytime I notice another woman in any way so I told her I didn't notice. Today she was saying that I was gay (jokingly) and only noticed guys. Like an idiot I opened my mouth and told her I always noticed girls and told her I had noticed the girl and the grey top to prove my point. Now she's really upset and says she can never trust me again. Help

Can you condense the text into three sentences or less?
