How often do you tell your SO I love you.

I'm not just saying love you on the phone or goodbye but actually look in their eyes and say I Love You. I asking because I do it all the time I'll do it in front of people I don't care. Recently my friend told me that that's weird and makes her feel uncomfortable because she doesn't do that with her SO. She told me that I use it too often but I think you can never say it to much she told me that it loses it's meaning do you agree with her? Or me?
