Spencer put it better than I would have. once I stopped worrying about how often it goes somewhere, serious dating got a lot simpler. In practice, serious dating lives or dies on how much of it's real. The part people underrate about serious dating is the fake-account issue.
Two people can have opposite results with serious dating purely because of the conversion from match to conversation.
The honest tradeoff with serious dating is the practical side against convenience. Nobody warns you that serious dating depends so heavily on the hit rate.
Anyway, that's my read on best serious dating apps for finding a husband/wife.
