Being forced to pick between friends and girlfriend

Imma make this short and sweet. So, basically, as stated above, I have to pick between my friends and girlfriend. I’ve been with my girlfriend for two months. Known her for three. She’s different from my friends in many ways. First our relationship was a little bit rocky because we were getting to know each other. But over time, the more we get to know each other, the better we get along. My friends heard about the problems because I talk to them for advice. They think she’s a bad influence and that she’s going to hurt me. My friend(let’s call her G) thinks that my girlfriend will hurt me. Like physically. And my other friend( Let’s call him K) thinks that she’s too immature and that she’s going to stunt me in growth. I’ve had many arguments with them about it. Apparently I’ve been making them feel like they aren’t good enough because I talk about her so much. She’s been trying to get better. Yes, she’s aggressive, a little bitter and has cringy humor, But I know she loves me. She cares, a lot. She even stopped smoking for me. We talked through our problems and make sure to understand each other and listen. To be honest, I don’t know what to do. I know that she’s trying and I absolutely don’t want to break up with her. I don’t want to hurt her and I don’t want to be hurting myself. I told K I will do it next week but, after spending time with her I just realized I can’t. I held my girlfriend for almost 20 minutes because she was crying so much because I said “ we need to talk.” And she assumed the worst. Throughout the week she was talking about so many things that were going to happen in the future and I kept thinking about how everything we’re doing this week is the last time we’re going to ever do them. And I feel so cornered. The thought of it destroys me inside but if I don’t, I’m going to lose my friends’ trust and possibly them. i’m so stuck right now and it’s hurting me tremendously. I’m being torn apart and polarized inside. I don’t want to lose my friends(they are basically my family and know me very well), but I don’t want to lose my girlfriend. What do I do? Tl;dr: Friends don’t like girlfriend, girlfriend doesn’t like friends. Stuck in between.
