I need help decoding a man’s behavior

So I feel like I’m going insane. I matched with a guy on tinder that I thought was hot and easy to talk to so I asked him what he was looking for. He said he was looking for something long term, either a fwb or a relationship. I asked if he wanted to be fwb and then just see where it goes, he said yes. So I met him a week after talking and we went to his place, we talked a little, watched a movie, did the deed, he kissed me on the forehead and then we cuddled. I was so confused and shocked by the forehead kiss that I didn’t know what to do or say. But then we did the deed again, and again and again, and then he fell asleep and I couldn’t sleep because I was thinking about how he fucking kissed my forehead. I put it away in the back of my head and told myself “he probably just does that to everyone he sleeps with”. Well this wasn’t the only weird thing he did. He always wants me to sleep over which I’ve heard is a nono when it comes to fwb relationships. He constantly wants to kiss me and touch me non sexually like he cares about me which is also a nono. He’s always asking me if there’s something I need or if I’m okey. I might be overthinking because nobody’s ever shown me normal human decency, but I don’t think it’s normal for a fwb to care so much. We actually never talked about what our limits are (dumb ik but he’s hot and I was horny so I wasn’t thinking straight and then suddenly it was too late) so I just go with what he wants. But now he’s kind of blurring the line between fwb and gf/bf a little to much. We’ve been fwb for three months now, is there a possibility that he thinks we’re in a relationship even though we haven’t talked about it? Like I’m talking to other guys because I thought we were only having sex and hanging out, but now I kinda feel bad…
