does he love me or what?

[Roro]

OK... I've been with this guy (let's call him N )for 9 months we were best friends before that for about year and a half he is very sensitive,romantic guy hr is very honest hot and caring person
BUT he doesn't have sisters he only has one brother and he doesn't like him so much
he always wants to have best female friends like sisters and now he has tow best girl friends (let's call them H and R) and he loves them so much he tells them (i love you i miss you ur pretty and beautiful) and stuff like that and he believes that friendship is more important than love because friends don't fight and wont loose each other but he fall in love with me so we are dating
i feel so jealous of his friends but i can't say anything because i know he is not cheating on me at all
BUT tow days ago we were on Facebook and chatting his 2 best friends were online too so he was chatting with them too(i'm best friends with them too but i didn't want to talk with them that day)
he was ignoring me and barely talked to me then he said bye and went offline
i have his password so i asked his permission to open his account
i read what they were talking and he was saying i love you to (H) and he was calling her pretty and said her eyes,her chicks and her body is beautiful but ot in romantic way just joking and(H) was saying( stop it don't say that you made me blush and stuff like that) and he was saying i love to ® too when i was waiting him to talk to me and i thought he is mad or tired but now i don't know what he was thinking
so heeeeeeelp what should i doooo
ah i forgot wene we were just friends he told me that he loves me and i'm the greatest sister in the world
so help
when we kiss it's so hot and he can't get enough from my lips
we hold hands and hug a lot
i'm afraid he only sees me as a sister
