What is he in it for?

He finds his way near me all the time at work, plans to take his lunch at the same time as me so we can take it together. He took me out one night and went in for a kiss and I rejected him (previous post explains why). The next day he brought food to me and we talked in the car for hours.. He'll play with my hair and stare at me a lot. He tells me personal stories and asks about mine. He texts me daily if we haven't seen each other and he also has given me one of his bracelets and I'm not really sure how I should take that. He asked what I'm doing on Monday because he wants to do something during the day with me. Last night we went to the movies and he was lightly rubbing my leg and held my hand And at the end of the night he gave me multiple hugs and later on texted me saying I feel good in his arms. But he has offered to give me a massage which made me kinda turned off because I take that as him trying to have sex with me. I'm just not sure if all of this is true feelings or a part of seduction. I have a tendency of overthinking... Want to hear someone's opinion
