Fell into a trap

Before I start: I’ve hooked up before in the past and didn’t catch feelings.

I met this guy on an app, he lives close to me and I jokingly asked him to Netflix and chill LOL I ended up going to his house without expecting much (emotionally wise) I kind of just wanted to get in and leave.

He didn’t want to do that, instead he showed me around his apt then asked to cuddle. So we laid in bed cuddling then he told me he wanted to get to know me so we got to know each other while cuddling.

Throughout the whole time he kept complementing me and treating me the way ive been wanting to be treated by someone for so long. (Leaving out the hookup part ofc)

We kind of just laid there looking into each others eyes for a while and making silly jokes. After everything went down he said he wants to make more time for me and asked if I wanted to stay to hang out with his friends (he was going to do a photoshoot.) I was just taken a back by how he was towards me.

My questions:

Should I tell him how I feel? (I only saw him once and I feel this way)

How do I know if these actions were genuine and not him just playing with me? (we texted the Day after and that’s it)

Is the typical f-boy act?

I need some insight! Plz pop my bubble LOL
