Yes, it's true but it suffers from the common issue of using the term "love" to refer specifically to romantic relationships, which is a sad commentary on how much real love of people for each other is lacking in society. And romantic relationships are about the fakest love there is. It's mainly just an emotional "business" exchange. It's transactional. And that's exactly why the statement is true that romantic love is .... oh, I had misread the statement. I thought it said most uncomfortable. So, now I'm not sure what the statement means or which kind of "love" they're talking about. But no, love is definitely not most comfortable when it goes one way either way.
