Some context of your own situation and experience would be useful to frame things a bit better
Some claim they are still madly in love. Drill down a bit and what it really means is "I'm happily married and accept that over time the love fades and you become less physically attracted to your partner". Whether people want to call this "still in love" or "out of love" is subjective, but underneath its still all the same. But "madly in love", yeah bullshit, that's just people kidding themselves or maintaining an exterior facade.
