Should I support my girlfriend in selling socks for extra money?

My girlfriend (22) and I (23) have been together for almost three years. During this time, she has shared personal stories about how she used to sell her socks and make a good amount of money from it. She's mentioned several times that she's struggling financially, even though she has a full-time job that pays poorly and requires her to commute over 100 miles daily. She’s sticking with this job because it’s currently the only one within a 50-mile radius that will provide her with valuable experience for her career. She understands my discomfort about the sock selling, but to her, it’s not sexual; it’s just a straightforward transaction — wear them, send them off, get paid, and move on. While the idea of what others might do with them is a bit off-putting to me, I can see that it has the potential to generate considerable income and that her previous experience in this area could give her a head start. I’m feeling conflicted and could use some advice. On one hand, there's the allure of good money, but on the other hand, it feels strange. Since she can separate her feelings about it so easily, I’m left wondering if I can do the same. **TL;DR**: My girlfriend wants to start selling socks online again to earn extra money. She views it as a practical solution to her financial struggles, while I feel uneasy about it. I'm uncertain whether I should support her decision.
