Love makes you do strange things. One of them is that you lower your boundaries. Things that one wouldn't normally do become very doable indeed, and things one would never tell anyone else are suddenly open for deep discussions. Being in love is truly an eye-opening experience.
You may recognize this from your own experience.
One of the boundaries that suddenly gets lowered is the infoecological one. Before love happened, you walked about in your own context and vaguely knew about things outside of it. After, you find yourself listening to new music, reading new texts, visiting new places and on the whole doing the strangest new things. Things you really wouldn't have imagined doing in that state of things before love struck, but started doing as a result of getting to know the other.
Suddenly, you find yourself interested in all manner of interesting situations. I'm sure you can think back to loves past and find examples of these.
The thing is, of course, that you really don't need to be in love to learn new things and add new loci to your internal context. It's a very effective motivator, to be sure, but it's not necessary by any means.
We could all do with a bit less boundaries in our lives, I think. And the infoecological ones are the easiest to lower. The rest follows, once you get going.
