Trouble finding a motivated co-founder

For context, I'm a college student running a consumer mobile app business. I've been working on my own apps solo for about 6 months (both development and marketing), and since I'm majoring in engineering, it's been quite hard to balance running this business with my studies.This is what originally led me to seek a co-founder in the consumer mobile app space who's strong in UGC/distribution. The problem is that It's very hard for me to find someone who actually cares and is willing to put in the work.Some past scenarios:1) I made a profile on the YC Co-founder matching site and got matched with a guy who eventually ghosted me after two weeks. I got matched with a couple of other people as well, but they never answered any of my introduction DMs2) I met another guy on this one app called "Ambitious" who seemed pretty motivated (he was also a student) and was also interested in mobile apps. But after creating literally 1 single video, he said that he didn't have the time for this and left.I've tried talking to other students at my university as well, but I don't really go to a prestigious school or one that's known for cs/tech, so not many people are interested in startups or stuff…
