How can I, a 19-year-old female, inform my parents about my boyfriend, a 22-year-old male, considering that they don't approve of him?

I'm using a burner account to share this. We began as coworkers and friends, but eventually realized we had feelings for each other and started dating. He has joined me on several family trips, always presenting himself as “just a friend.” On one of those trips last year, he had some weed, which my parents strongly disapproved of, and it almost led them to make me stop seeing him. However, after some time, we were able to spend time together again, and we've been officially dating since then. He has joined my family on another trip recently, and everything seems to be going well. My parents are aware that we hang out alone and that we have plans for an upcoming trip with friends. I really want to tell them that I’m dating him because I feel mature enough to do so, and he has been supportive of my family and me. However, I'm unsure of how they will react since he attends community college while I’m at a university, which seems to be an issue for them. It seems like they’ve moved past that previous incident, and he has shown he’s responsible since then, but I’m still feeling conflicted. After that situation, they seemed to think we might be dating and were very much against that idea. What should I do? Keeping this a secret has been challenging for me at times.
