AITA for not telling my girlfriend about the proposes of my ex to be with her again?

Throwaway account.<br><br>My girlfriend (25) and I (27) have been dating for almost 1 year and everything has been great.<br><br>Before her, I was in a relationship with another girl named Anna for 6 years. We were in a long distance relationship and I moved to be with her after college to start a life together, 1 year later I proposed to her but she refused to marry me and said she didn't wanted to be in a relationship anymore. I was devastate and decided to move back to my home town. She tried to make me stay but I didn't wanted to be close to her. We didn't have any contact for 8 months. 3 months after meeting my current girlfriend, Anna contacted me again, she said she regretted not marrying me and she wanted me back. I told her I was seeing someone else and she told me that she was going to wait for me, that she was going to make me change my mind.<br><br>She contacted me multiple times but I didn't give her any hope. I didn't mentioned any of this to my girlfriend because I didn't wanted her to be uncomfortable but last week, Anna told me that she was going to travel to my home town to talk to me in person. She arrived yesterday and when I was leaving work, she was in front of me, she hugged me and kissed me and she told me that she wanted to marry me and be with me. I removed myself from her arms and told her that I didn't loved her anymore but she said that it didn't matter, she was going to make me loved her again.<br><br>At that moment my girlfriend arrived and was surprised to see her and asked me who was she and I told her that it was Anna, my ex girlfriend, she didn't believed me and asked Anna to confirm and she did. She was very upset and she wanted to know why she was there and I told her that she wanted to marry me but I told her I didn't loved her anymore. She was more upset and she told me that I should have told her about Anna's proposes and I told her that I didn't wanted her to be uncomfortable but she told me that I should have told her because she had the right to know about someone that was trying to get me to leave her. She left and I went after her but she didn't wanted to hear anything and she went home alone and didn't wanted me to come with her.<br><br>We talked on the phone today and she told me that she feels like I don't valued her feelings at all and I'm playing with her. I told her that wasn't my intention but she told me that I should have been honest from the beginning and tell her the truth about Anna. Now she is doubting my love for her and she told me she needs time to think about what she wants to do with us.<br><br>So AITA for not telling her about Anna's proposes?<br><br>Edit: Anna and I ended for good 1 year ago. She's been trying to get me back for that long and now she is trying to get me back by any means. Anna holds a high position in a big company and it has been a great help for her proposes. <br><br>Please don't be rude or insult Anna in any way. I don't condone rudeness or any kind of insult to anyone.
