love life's peek-a-boo

what a rare moment I put a love life post on my blog. yeah, at least, my post is merely about broken-hearted condition. silly things after one year and months I broke up. that's my bad anyway :|
btw, gah! I don't know where I have to start telling this peek-a-boo!

let start introducing.
I'm in (maybe) kind of like with a guy. can't describe about him furthermore.
realized about it since April. and being normal in actions or responses to him.
the hardest problem is I can't do any jobs without him around. always meet him in any opportunity, and becomes a partner in some jobs. absolutely, my religious service won't wait me until the day I can stay away from him. such a professional connection.
I don't know why I like him. or maybe it already improves into love with affections or something else (?)
okay then, he's the charming one. he gets the charisma. he's the calmest one. he's the well-controlled one. he has something indescribable things which make me speechless. it's not about his hobby, or his passion. but there's a falling-cause thingy on him.
recently, I felt he kind of giving a sign about that-falling-thingy to me, either. I honestly say that I don't put a high hope to him, indeed because I realize he still has a feeling for a girl (don't know about it now). some people say, he doesn't anymore. some people already feel a weird thing between he and I.
someone told be bravely: "I see something different with him when he's with you. something I never see except for the ex-girl he liked."
don't want to be too confidence about it, I just let it flow. but that thing disturbed me a bit much. actually, I feel it too. he teases me physically and he doesn't do that to other girls. sometimes I see and look for that thing.
the last weird thing is we were messaged to talk about the future of our jobs, for 2 days and this is the first time I saw him enthusiastically talking about something. teasing each other by message. it was the weird one.
but then, he changed again to be the plegmatis one who is so ignorant.
it becomes a usual thing that I admit about him.
in the end, I don't know how to response and react. I'm just afraid of misunderstanding :(
