Sugar daddy but... I'm in a relationship...

I'm a student with a job that doesn't pay me enough to save up for tuition fees and preparation to move out of my parents house. I have been currently trying to find ways to get money. I spoke to my friend who told me about the seeking arrangement app. I signed up and in my profil made it strictly clear that I am only there to Accompany the "sugar daddies" over dinner or other events in order to improve their image and make them look successful (arm candy) and no sexual relationship is to take place. Before meeting them of course I will take safety proportions as in have a friend secretly follow us around to make sure I'm safe ect. My boyfriend isn't happy with the idea he says it makes him feel like he's not good enough and that it's basically cheating. Really I'm just trying to make money for both of us I have no feelings for the older men it's simply a job. What do you think?
