just seen the second episode, but yes and no.
after their honeymoons they were all put up in their own houses/flats for a month, after that they had to decide if they wanted to stay together or divorce. 3 out of 4 couples decided to stay together (but not all could live together straight away).
then, after another 5 months, 1 couple were still together and another (who all along seemed to be the only genuinely happy/compatible ones) decided to ‘take a break’ after they’d both moved to a new city together and been stressed out.
the ones who were still together weren’t sure what they were going to do after the one month review because she didn’t want to have to move out of london because it would mean she would then ‘never move back’. anyway, he moved to london and his job (in bournemouth?) was up in the air. they both could have moved somewhere closer to reading (where he could have transferred to) but she didn’t want to leave london. dunno what he was doing. on leave?
the couple who broke up after a month didn’t ever see each other as romantic partners, plus he was a smoker and she hated that . then at the end of the program he was living aone and still wore his ring (she didn’t, they were separated and planned to divorce) it was a bit weird because she obviously never had feelings for him but he was clearly really affected by the whole thing/latched on to the idea it could work eventually
