What to do when a guy ask you not to get attached? Should I continue seeing him?

So I met this guy recently and I have feelings for him. it’s been a month and since the beginning he is telling me not to get attached as he is scared for me. He asked me whether we can stay friends after all this.
So last night we got physical, and after that he told me let’s see where it goes, and asked me to stay friends no matter what well I already confessed my feelings.
I appreciate his honesty but I m scared of breaking my heart, he reminds me all the time not to get attached & asks me lets get to know each other and then we will see where it goes ( and tbh I don’t feel like there will be any future)
What should I do, shall I stay friends & keep seeing this guy or else shall I start seeing someone new? I m really confused!!
