Interesting idea for sure, but how do you distinguish between users successfully starting a relationship and those just not using the service anymore? Can I say "I did not find a relationship with that person and I'm not interested in looking again for a while"? If so, what would stop people from saying that even if it's untrue? Also, it means zero monetization for people looking for single encounters and/or flings, which I would bet is a meaningful portion of Tinder's income.
