How does he reveal that he’s been lying about his job?

"My girlfriend and I have been together for 4 months. When I matched with her online, I felt like she was out of my league, so I lied about my job. I'm not proud of what I do, and I don't make much money doing it. I know as things get more serious I need to tell her the truth, but I don't want her to lose any trust in me."
