How do I get my girlfriend to knock off this annoying habit?

Her and I have been together for 3 years now, but lately she keeps saying this phrase. She’ll say it to me randomly, out of nowhere, a few times a day. <br><br>“I love you more than you love yourself.”<br><br>I’m not trying to sound like an asshole or anything, but it gets on my nerves. I’ll be in the middle of something important, and she’ll just blurt it out. It’s just so annoying. <br><br>And to top it off, she says that exact phrase every time. The exact same words. I don’t even think she realizes she’s doing it, tbh. I’ve tried pointing it out to her, but she didn’t respond. It really bothers me, and I don’t know what to do.
