Should I continue trying or lay back? Don’t want to be hurt anymore

My guy interest came over for breakfast and a movie. He didn’t kiss me (like I was hoping would happen) once and only put his arm around me after I asked to lay on his shoulder. Later on in the day after he left, I asked if we are aiming to be more than friends or just friends because I wasn’t sure if I crossed a line asking to lay on his shoulder. He replied: “Well you seem like a good girl, we can see where it goes. It wasn’t too much lol, we’re adults. I might say something you don’t like and you’ll drop me. Have to be careful around you. Already passed the dog test (he met my dogs and they loved him)”. We technically met in middle school and been in each other’s socials for years but started talking when we matched on Tinder. He bought a cake from my business. Asked me to the arboretum. And made plans for next week to go to the park with my dogs. Maybe I’m used to moving faster but idk if he has other interests or something. It has been a week and a half of continuing conversations. I feel myself really liking him but I don’t want to continue if I’m going to end up wasting my time. Any advice on how I can avoid being hurt?
