Why is he showing this kind of affection after ending friends with benifits?

So my best friend and I finally opened up about our feelings two months ago. Ive been madly in love with this kind for almost 2 years. Hes everything I wanted. When we opened up he told me he wanted something but not yet because he was working 2 summer jobs and he wanted to be sure he had time for me. We both agreed it wasnt our time for a relationship. I stayed at his house for 2 weeks while I was going through some family issues and we ended up having sex. I gave him oral a few times to(sadly i didnt recieve it back lol). What i found weird was he never kissed me, not on the lips, no where, and weve never made out. We slept together every night and cuddled and had pillow fights and we seemed really happy together. But once we were with out friends he acted as nothing more but a friend to me. Eventually, last week I told him what we were doing condradicts my self worth and that we need to be just friends. I could tell that his intentions for me were different than what he claimed them to be.I could tell he didnt want a relationship, and he just wanted to be friends with benifits. I agreed to being fwb with him only because im extremely attracted to him. Once I told him we need to stay friends he just said okay and didnt seem to be very effected by it. My friends and i came to his house for a little party the other night and i spent the night because i got locked out of my house. Everyone left at 5 am and him and i were sitting in the basement together watching spongebob.
