Likeing someone

I'm currently talking to someone new and I honestly want this man to like me so bad. He says he does but my insecurities tell me he doesn't and will eventually end things yk. But I need to let go of the negative thoughts because I genuinely think he likes me. He calls me pretty, beautiful, and cute and just makes me feel seen no matter the issue. I honestly wanna start something with him and I see myself with him in the future, however everyone knows the 3 month rule so I hope it doesn't affect us.
