Well we've certainly come a long way from fiddler on the roof, haven't we? Or the best romantic prospect being either your cousin, or the farmer girl that lives a mile away? I think that theory holds.

Yea, in my experience that's how a huge swath of relationships usually work, especially for people who haven't been in many relationships or who have big enough relationship gaps that they feel the need to cling. People getting caught in relationships that aren't all that great but "hey, wtf else are we gonna do, at least we aren't tearing each other's throats out, right? Maybe having a baby will help us love each other." We've all seen it, many of us have lived it.
I'm arguing that the proliferation of dating apps is helping that go away. Either because a highly specialized interests based site like OkCupid lets you zero in on quite nearly the perfect partner, or because you can shotgun across a zero cost app like tinder, you're far more likely to find an actual meaningful relationship.
For the record, I know there's a higher tier of relationship than "familiarity breeds love" due to personal experience.
