My best friend said "I love you"?

So I'll give you some background info before I get to the main question. I've known my best friend since the summer after my freshman year in high school. I had actually thought he was cute and asked for his number. we talked for awhile, hung out, a few kisses here and there but nothing serious we were in high school and it only lasted a couple months. We're both 23 now. We decided that we loved being around eachother but that we werent meant to be a couple, complete opposites really; hes the sports fanatic mellow guy, and I'm more do my own thing stubborn type ha. But we truly became best friends, we were and still are inseparable, tell eachother things we've never told anyone, he talks to me about girls, I've talked to him about guys etc and he's actually going to be one of my "bridespeople" lol (please no rude remarks about that he doesn't really want to but knows it means alot to me so hes going along with it thanks). Anyway about a year ago i moved in with my boyfriend who is now my fianc�e actually, we started hanging out less but still do, we talk alot but obviously I'm getting married so mt fianc�e is #1 guy (I dont want my fianc�e to be worried some guys do) Anyway a couple days ago my friend and I were hanging out he was helping me detail my car when he found this note that a guy from work had written me a month before stuffed under my seat (I'm a paper hoarder I rarely through things out lol) the guy from my work wrote that he really liked me (basically a love note he was a bit weird/shy so i was nicer to him at work than most people and he took it the wrong way which I explained after he gave it to me) anyway so my friend was reading this laughing saying that this guy sounded like a chick blah blah then he read out loud from the note "I really like the way you curl your hair at work sometimes" he started laughing so did I but then he looked at me and said "Thats like me telling you that I love you because you straighten your hair" then I laughed and so did he. But I thought it was odd. He threw "love" into it when the note hadn't said that, and even though we're very close hes never told me he loves me. Is this odd am I taking it out of context or is there a meaning behind this? And i should add that I do have another good friend (whom I've known since middle school) who is convinced he still cares for me. I love my fianc�e and do not want to leave him, but do not want to be put in any type of awkward situation. If anyone has advicee it'd be helpful thanks.
