Short list why i think so:

he responded just "alright" when i wanted to sleep on his chest
he said "ok. I guess it will make you happy" when I wanted us to date
he spends a lot of time with another woman
when I asked him if he wants to be my husband in the future or now he just said - no words. ofc I can marry you. Its very easy (he didn't say he wants)
He is caring, smart, hot, interesting and I am in love with him bur... Before few days I told him I can leave him be if i am annoying himand that i dont seem to be what he wants. He was silent for a day and then called me 5 times in a row
