How do you know if a guy like you?

We have been seeing each other a little over 2 maybe 3 weeks now. We went on our first date only hugged. Second date we kissed. And we hang out casually now we make out a bit and hold hands. We greet each other with a kiss and say goodbye with a kiss. He texts me good morning and goodnight. We have good conversation and haven’t stopped texting since we first met. (We both work so of course not during work)Idk it’s like I feel like he does. But I just put myself down a lot and feel like he won’t stay around if we don’t have sex. (He hasn’t pressured me or even talked about it) I guess I’m just used to assholes who only want sex. Or that I’m not pretty enough. 🤷‍♀️
