<human>: Been with this girl about three months and she's been in her home state for the holidays. She just found out her ex-bf of four years was gay, and that why he broke it off.

So for the past two days, she's just been in shock and thinking about it whenever I talk with her. She says she felt betrayed and lied to and it brought up a lot of memories. I listened to her and was supportive and all that.

Logically, I totally get it and I'd be a little weirded out about it too. I'm doing everything I should to be understanding of how she feels. Emotionally though, I'm a little annoyed about it because I honestly don't give a single shit about her ex or talking about him. I don't fear her leaving me or anything, but something about her thinking about it so much bothers me.

How should I feel about this? Obviously, if it goes on for a long time, that's a problem. I guess I should just ride it out and hope she gets over it soon?

Can you condense the text into a few key points?
<bot>: GF finds out her ex was gay and she's very bothered by it. And now I'm bothered that she cares so much. How should I feel?
