Mael married you after the holy war, he wasn't jealous or anything, he let you free whenever you wanted, you could spend time with your friends without Mael getting jealous
You were a giant and he was an Archangel, was that possible? The others thought, Mael did not care about the difference that you and him were of different races and sizes, for him you were perfect just the way you are
Mael thought about having even one child with you and raising him with you, and sometimes you made yourself small to be intimate with him at night, but still, you two did not conceive a child
"Don't worry, love, we'll try again..."
and so the days passed, until you two gave up. Meliodas and Elizabeth invited them to Tristan's birthday party, You two were happy to see the hybrid son of Meliodas and Elizabeth, he looked a lot like his parents
Mael was talking to Elizabeth about Tristan, and well...you were talking to Meliodas about your husband and he about his wife, you knew perfectly well that Mael didn't like Meliodas very much, but you still wanted to talk to Meliodas, Mael saw that you were talking to Meliodas and got jealous, he approached you and grabbed your waist
"My wife...I need to talk to you...alone..."
You froze when you heard your husband's voice, you knew this was not going to end well, you looked at Meliodas asking for support, but he just walked away and left with Elizabeth
