EastEnders aired emotional scenes on Tuesday, as Whitney Dean and Callum Highway's wedding fell apart.
Whitney jilted her groom in a twist, moments after confronting his secret lover Ben Mitchell who had questioned why she wanted to go through with it knowing he was gay.
Even her stepmother Bianca couldn't sway her mind initially, telling Whit she couldn't change who Callum really was.
Whitney made it all the way to Callum who was waiting in the venue, leaving fans believing the wedding would go ahead - despite many viewers wanting Ballum to happen.
But after Callum said his vows, it was Whitney's turn to declare her feelings.
It's then that she suddenly became overwhelmed and looked at Callum before telling him: "I'm so sorry."
With only Bianca, Callum and Whitney knowing the situation within that room, the congregation were left stunned as the bride suddenly legged it out the room.
Callum went to follow her begging her to come back, but Whit got into her wedding car and drove off.
Later on, Callum found her at the flat and begged her to give him another chance - and it's then that she realised something.
Asking if Callum was in love with Ben, she recalled the letters he had kept from is ex-army pal called Chris.
Chris, who recently died, was in love with Callum and the pair exchanged letters - which he kept in a box only discovered recently.
Whitney then realised who Chris really was initially believing him to be a girl Callum used to love, and it's then that she finally realised he was gay.
In emotional scenes, Whitney told him that she couldn't force him to be someone he wasn't, before she let him go.
EastEnders airs Mondays and Fridays at 8pm, and Tuesdays and Thursdays at 7:30pm on BBC One.
