Is it normal he feels this way?guys please help me.beg your advice

Guys please help me.Promise I will keep short.We had "No strings attached"relationship with this guy.But it wasnt just for sex.We understood and talked to each other more than to anyone else.After 8 month he spilt with me and we remained friends.A month ago on a language competition i won two vacation tickets and we wen together just as friends.There he kissed me,and when i said we are just friends he said that he didnt want to come just because he wasnt sure that he will be just friends with me.I write what he said and beg your advice cause I get nothing
"I spelt with u just because there came a time that sleeping with u became a duty for me,never think that there was any other girl,cause i would never change u with another one,I swear with my moms life I didnt sleep with anyone else after u,I dont know what i want,and now the thing i am most afraid of is that i will want u again when we go back.U are the one that understands me completely in this world.I am artifical in front of everyone besides u,with u i feel so natural,and this is the way i want to live all my life.I am sure this is not love,maybe this is passion"Then one night we were talking and he asked"Will u get married to me if we love each other one day".we lived as lovers that 7 days even had sex but planed to remain friends as soon as we come back.When getting back He said "Please promise that u wont get sad,why i say this to you if i feel bad already".Guys please give advice.I want to add that i believe what he says,he is a very unique guy and all the way back he hold me in his arms,kissed me,treated very gently.Please what do u think does he love me or not?Maybe he loves me but cant understand?The song "Love the way u lie"was our song but we never pay attention at lyrics.on our trip we were always listening to the songs Part 2.There when Rihanna says u will always be my hero even though u have lost your mind,he asked will i be your Hero?i said no.He said i will. I said then I will be your heroine.He said sure if i dont find better one.All the way back he listened to James Blunt songs and asked me to come out of the bus to hear the song in the rain.
