<human>: Can you give me a shortened version of the text?

I have been friends with [18M] for a year now, and in August at a party we made out and agreed to take things casually, see where things go, etc. No commitment. 

We end up not seeing each other until college resumed. We talked during the first week of college and he admitted that he irrationally thought that I wanted a relationship, and that he was sorry for distancing himself. He admitted that he was afraid of commitment due to his last serious relationship that turned sour. I told him that I wasn't necessarily looking for commitment, and we could have fun, see where things led us -- and if a relationship came out of it all, well that would just be a bonus. 

Since having that conversation, he has taken me out on dates, to parties, and greets me with a kiss when we see each other. He kisses me in public, in front of his friends. He has invited me over to his house, where I have met his parents and dined with them. 

We have been seeing each other for three weeks now, and have fooled around, cuddled, and had sex. I guess I'm just confused because it seemed to me as though we had a sort FWB arrangement, but from the start he has been really affectionate, and hasn't been afraid to show his affection in public. 

Don't get me wrong, I don't mind this affection. But I'm getting to a point where I would like to know where we stand. Then again, I'm hesitant to ask if we're exclusive since he made a point of telling me that he is afraid of commitment and I really don't want to mess up what we have now. I really like what I have with him now, and don't want to mess it up just so that I can have a definitive label on what we are...

Thoughts?
<bot>: Thought I had a sort of FWB arrangement, but he's very affectionate in public. I'm afraid to ask where we stand since he has stated that he is afraid of commitment.
