Cam model

So my boyfriend and I have even dating since we were sophomores in high school. We are now sophomores in college. We go to different colleges but they are like 40 minutes apart. He has had an apartment his parents pay for since freshman year but I just recently started renting my own apartment. We can’t live together because the distance one of us would have to travel for class is just too much. My rent is extremely expensive, so my 2 part time jobs are not enough to pay rent, utilities, gas for my car, and have money left over to go out with. I have the cheapest apartment in the area. So I have become a cam model. The money I make on that pays for all of my rent and utilities, my part time jobs pay for the test and tuition for college. I DO NOT get nude on camera. I dont do crazy sexual things either, I will dirty talk and small things like that during my shows but that is it. But I haven’t told my boyfriend this. I feel like I need to tell him. It’s been 3 months of me doing this and he doesn’t know. I want to tell him I just don’t know how to, or how he will react. Should I tell him? And if so, how? And what if he reacts bad? No one knows about me being a cam model.
