Torn between my guy and my family 💔

Okay y’all. I need some advice... my parents DO NOT approve of the guy I am talking to. They actually HATE him (there is a past)... however, I’m hoping one day they could look past all of that. I really like him. Like A LOT A LOT!!!! I’m pretty sure I am in love with him! This past time I told my parents I was seeing him, they went off! I mean, went off! They basically told me it was him or them. I’m still in college and still depend on them for a lot of stuff. They think I’ve ended things with him, even though I am still talking to him. I hate hiding things from them. I feel like I’m doing something bad, and I despise that feeling. I am just at odds and don’t know what to do?? Anyone else been in this situation, and feel like helping a sister out??

When I say there was a past. The past happened before either of us were born between our parents (his dad my mom).
