I'm trying my best to express my intent early on in interactions but I notice that I come across a little bit needy. Last week i told a girl that she has a really nice smile, but when i said it something just did not feel right. I felt like i was giving off a nice guy vibe. How do you express your intent in an alpha way? In other words, how do you tell a girl that you're into her without coming off desperate/needy? I want to remain as authentic as possible without falling into the "nice guy" trap
