Her main objective would have been that both JB and JM would tire of tooing and froing,thus either one would have found someone else at closer quarters.
There'd have been a clause,June wasn't stupid. Controlling people usually have everything worked out to their advantage.
Are you saying you'd have been prepared to GIVE, a house/flat, lock, stock and free/leasehold, to an offspring's partner, risk the relationship breaking up and the ex walking away with the money you'd paid, all because you wouldn't have them sleeping together? I see NOTHING wrong in June wishing to maintain control of it. I concur that she hoped the distance would break them up.
