I believe something will happen in s7, maybe they just don't know yet! I understand Ellie's embarassment though, she's 9 years older than him! But Meera is maybe 4 years older than Bran, and we're talking about Middle Age, so there might be room for that
Well I think if he were to marry anyone in the future he'd probably marry Meera but he might not marry anyone and live the rest of his days as the Raven beyond the wall which would be very sad
