They both knew things would end, the relationship was a mess and Alex couldn't take it anymore, even though he loved her with all his heart. He would never stop loving her. Yes, they were friends, but it wasn't the same, he wanted to be more than just her "friend", he wanted to be the one again who made her smile, laugh, and how her eyes lit up when he kissed her and how she looked at him as if he were the most important person in her world. He missed her, a lot. But by now he had moved on, he was in a new relationship. It hadn't taken him long to replace her. Six years had passed since that event and she was still friends with them and often went to concerts but only exclusively for Matt, Nick and Jamie. Not for him.
There wasn't a friendly relationship between her and Louise, how can you make friends with your boyfriend's ex? And some people hated her for that and compared them, saying there was cheating and all that fan shit, so it made Louise hate her, the fandom also split in two but not that the guys cared, usually she only went to concerts to say hello to Matt and his daughter, who cared about her as if she were an aunt, but honestly she didn't want to have anything to do with Alex, which was understandable.
Alex was holding Louise's waist while they talked to the others. They had just finished a concert and it was late at night, but they were still there chatting. Alex looked around and saw her coming out of the gate in a bit of a hurry as if she didn't want to see any of them but Amelia ran to her "Auntie!" the little girl screamed and hugged her legs making her stop and Matt tried to bring his daughter back to him but by now they had started a conversation, Alex knew how much she wanted to be a mother and it melted his heart to see her with children, but then his heart immediately broke, reminding him that they were no longer together and he couldn't think these things about her.
