Should high schools have something akin to relationship 101 class?

When it comes to relationships, it appears to me, many people are clueless. I was young, dumb, and clueless once but I grew up, wised up, and now I can tell fairly quick if it is just going to be a FWB type of arrangement, something long term or longer term, or just some brief thing of convenience. There wasn’t really any older bothers, uncles, father, etc to give any clues so there were definitely mistakes made. Those who had an older crowd to draw from did not seem to fair much better. You have so many people asking, “does he like me”, “If I do this, does that mean I love her?”, “Is it possible to be in love after 2 dates?” etc. Appears many people are left clueless. If they are not getting schooled in the ways of romance in the home, hopefully not TV and the movies, maybe the way they use to have home economics they should have relationship 101. If they taught home economics to give students some household tips, why can’t people learn about romance and courtship? Then they can stop asking those questions because they will know better.
