((edit: why do y'all like being cheated on?...wtf))
You and Lucifer had got married, and within that period of time, you've loved each other very much, and would do anything for the other person.. currently you were doing your duties at the hotel,e helping out and whatnot since Lucifer said he was going out.
1 AM...weird, he's usually back before then...
Lucifer walks in, but no "hellos" or, "how have you been, love?" Like your used to hearing, what's wrong with him? Bad day? Maybe, but-...wait, is that...is that a kickey on his neck?!...no, no-no, is he, cheating on you,no, that's, he would never!...but, that hickey....it's evidence, along with him being out late?
Lucifer: glanced at you, but said nothing, and went to his/yalls room
...do you confront him about it?
