Why am I afraid?

So I’ve been talking to this guy for two months. He’s not a stranger I knew of him before. But, he would always asks about my day, how I'm doing, things I'm into etc. Nothing really intimate yet. We went to the movies together he paid for my ticket I bought the popcorn, he kept staring at me and he held my hand. He sent me a text afterwards asking if I were home safely and that he wants to hang out again another day. I was kind of hesitant at first because I only want a physical relationship with him instead of this. But fast forward 2 months later. He started acting a little different after his cruise, he told me he got really sick. After he saw me hanging out with my friends he suddenly wants to get intimate. I told him yes we can get intimate as long as there’s no emotions afterwards or a relationship. He told me it’s whatever I want. Which pissed me off because it’s your emotions I don’t want him to feel sad. I asked him again and he was hesitant, and he said whatever you feel okay with I’m okay with. My friends were telling me that he’s into me not sexually but more than that. And, I’m not interested in pursuing a relationship right now because I’m getting my life together.

Why am I afraid?
