One way to possibly look at it - Cadash is no angel, they would likely be playing people for schmucks all the time as part of their simply being part of the Carta, this is maybe a sort of Karma for them? To fall for someone who is also a liar? A lot of my fellow Blackwall fans have romanced him with a Cadash, and in so many ways it fits (even if I personally didn't romance him with my Cadash.)
I don't know what to say, if you're really struggling to justify romancing him (this has not been the first time I've seen you deliberate over this) then perhaps the romance really isn't for you and maybe romancing nobody is the best option for this particular canon run?
