Hispanic chic qt gym

Theres this good lookin hispanic chic at my gym and everytime I look up shes staring at me constantly. Either she stares alot or she thinks im good looking. I got a feeling its the later. She has a husband or boyfriend whos a mexican. Hes nice to me and other guys but it seems he's mean to her. He yells in mexican at her. One time he told her to change his weights for him (in mexican) even though he could have done it and he said it rudely. I'm thinking about hitting on her is it appropriate? Of course Ill do it when hes not there. Sometimes she comes alone.
