I have a crush on a flatmate at university and I mean I have it really badly. I can't stop thinking about him, I have even lost sleep over it! Despite it being over just 2 weeks is a little crazy but I don't want to hang about and end up regretting not doing something there and then.

The reason that I started to like him was partly because 1: I find him attractive, 2: I like his personality and 3: At some points during our conversations online I swear he was flirting. I probably just misread it pretty badly.

So anyway, I decided to do something that is not like me at all and tell him how I felt. I came out of my comfort zone and I got rejected straight off course. I was told I was a lovely/nice girl, he wasn't ready for a relationship and that I am still a really good friend. Okay fine I respect that but something about it just bothered me. I didn't want to give up so easily. He barely knows me, he could end being really into me if he gave it the chance but of course I am not going to force anything on him. He's not even said if he finds me attractive or not. Unless him telling me, "I'm just really into Asian girls" was his way of telling me? I like Asian stuff! That should count towards something! Lol.

I have started leaving little notes here and there for him to find. Cute little things, he is a shy guy and I thought that they'd go down well. I certainly hoped that he would appreciate the effort and sentiment.
Well so far he hasn't said anything. I left him one note in Korean saying "I like you" since he's so obsessed with Asia, to show that I do pay attention and that I care. He said nothing.
So next I sent him a little text over our online chat in Portuguese (my mother language) in which I said to him: "I keep asking myself whether I should really give up. Tell me to stop?". He acknowledged he read it and used a translator but he never told me stop. And this is why I am here today. Why did he not tell me to stop? I made sure that Google would translate it correctly so he couldn't have missed it.

I hate to think I am just making him feel good about himself and that's why he didn't say anything. He really doesn't seem the type at all. He's very sweet.
I did notice though that when he said goodbye after I sent it, it felt a little too awkward after I sent that. He didn't say his goodbyes as he usually does.

Otherwise he seems to go about his daily business as if I have never revealed anything to him. I wonder if its at the back of his mind? Or whether it's something that just disappeared from his memory after while? Has it affected him? Does he really care?

I feel the notes may be a little too much (despite me thinking its romantic) after being told what I was told. These notes are part of my personality; I like doing these things for people. I don't want to seem like I am pushing but I just wanted him to give me a chance - a little one - just tiny. I wanted to show him that I do really care and it's not just some stupid silly crush. When I fall, I fall hard. He says he's never had a girlfriend and he seems shy so that may contribute to some things.

I don't have anyone to talk to about this so I am posting here hoping for someone to shed some light.
Thank you.

My opinion is to just be his friend. You can show him in little ways that you wish to be more, but don't go overboard with it or you may scare him of even if he is interested and just timid. Think of it this way to though, this is a crush and if you are very open and like to leave notes and do special things at some point you wouldn't be content not having them recognized. He may not be that type of guy. I honestly wish I could give you more advice, but I can say that what is meant to be will be and just try not to let your heart fall to quickly so that you aren't left picking up pieces if it doesn't turn out how you want.
