Did I just have sex with a trans woman?

Hello, I need to ask something. Maybe it's inappropriate I'm sorry, I don't know what to think so I need to ask to someone. I've been dating a woman for a few days. From the beginning I had been flattered for her attention because she's very beautiful. But I hate to lie, I've been so flattered that I have sex with her without a condom. I had sex again with her two days ago and yesterday I went to get tested for std's. While I was waiting for the results I started sending weird messages to her, asking how she lost her virginity and stuff like that, so yesterday she broke up with me. I don't know what is happening to me I feel bad, so I wrote her a message apologizing and telling her that I would be happy to see her soon. She wrote me back that she thinks I have been weird the last days because I discovered she's trans. I think it's true, how did I didn't realized it? She told me to "google it". I've been crying for hours. I feel ashamed, I don't know if it's because she's trans or because I discovered that I'm stupid. Honestly I didn't know because I didn't pay attention, sex are weird because I never saw her naked but I didn't care. And she has been on top of me so I didn't ask. I would had sex with her anytime she wanted because I didn't want to lose her attention. And I was so dumb that I didn't realize that she was trans when she broke up with me and told me that she would rather be with another woman than a man like me. I'm so ashamed, I want to die. Honestly I don't mind that she's trans, I feel bad that I didn't pay attention to anything. What is wrong with me? I don't know if I should feel bad because of what she said or that I didn't realize what she told me to google. I'm so dumb, I'm distracted and I don't pay attention to anything. I'm not good talking to people. So i want to know how did she know that I discovered that she's trans? I feel so bad, what did I do wrong?<br><br>Edit: Thanks for the Gold /u/Baltroc1234<br><br>Edit 2: Sorry guys but I feel like I need to end this post. Yesterday I woke up seeing a world surrounding me that was not real and it's not healthy. I want to thank you all for being kind. I wanted to say that when I was talking about being distracted and not paying attention, it's because it's how I feel every day, I'm distracted and I don't pay attention to anything so I'm not good talking to people or doing things in general. It's not because of her. And it's how I feel in general, so it's what I feel about the situation. I'm sorry if it's a problem for some people. Also I want to say, I don't care for the pronoun that she/they want to use, I don't think I should have a say on it because I don't know what they want to be called and how should I know that? But I want to say that I'm not going to argue about it, I'm sorry if I came across like I was going to argue. I don't know them so how can I know what they want to be called? And I don't want to be rude so I will not argue about it. I will use they pronoun because I don't know what they want to be called and they is a generic pronoun for everybody.
