Idk how i feel abt her

I broke up with my girlfriend of 3 years a little over a month ago. I never felt heartbroken, i loved her so much but never felt that pain everyone talks about, yet. I just met this girl a few days ago and weve went on 2 days and omg shes different. I loved my ex girlfriend so much, dont get me wrong but never felt what im feeling right now. Shes feels like the perfect girl. I dont know if what im feeling is actual true connection or just lust. Please help me out. I dont know if im doing the right thing and i dont wanna hurt her
