There’s this girl i really like but my closest friends don’t trust her. What should i do?

There’s this girl I really like but she has a bf. To make a long story short, she kissed me twice yesterday. She likes me and plans on breaking up with her bf, but when she kissed me she was still dating him. She wanted to kiss again today but I told her not until they’re broken up bc i thought about it and it’s cheating. She was okay with it and willing to wait. She hasn’t broken up with him yet, but said she plans to tonight. Technically, she cheated on him with me (I didn’t think about it in the heat of the moment or I would’ve told her to wait at that time). She’s really kind and caring and a lot of people like her and are friends with her. He treats her well in front of everyone else but treats her bad when others aren’t there. I’ve talked to multiple friends about this and they’re all split on it. My best friend thinks that it’s a bad idea and strongly suggests I don’t get involved and completely stop talking to her. They’re worried that i’ll get into a toxic relationship like they used to be in, but i don’t think that it’s fair that they compare this to their previous relationships which are completely different. My other best friend agrees with her and just doesnt want me to get hurt. My other friend and my older cousin think I should go ahead i that’s what i want, but be cautious. Another friend said I can go ahead and be cautious, but that the girl gives off bad vibes. My other cousin said not to trust her because she was willing to kiss me again today but that it’s ultimately my decision. I really like this girl and I don’t believe she’s a bad person, she’s just in a bad situation. Opinions?
