( Girls! ), honestly I need advice on this..?

[QaK]

I like this girl, she works as a Barista at Mcdonald's. I met her first time since couple weeks before, the day I met, asked her if she has a boyfriend - she smiled and didn't answer.

I'm not shy in public. I approached her, talk for a lil bit, she also gave some signs of interest like asking me "Where do you study?" and she kept looking into my eyes, too. But when I asked for her number, she said "Can u have my LINE(app) instead?", then I told her I don't use LINE and I only have Facebook. Then she told me she doesn't use Facebook and asked for my number instead as she told me like she just got a new number, couldn't remember her own number. So, I decided to write down my number on a note, and she said she would call.

After that, one week passed, she didn't call me so I went to Mcdonald's again for several times but didn't meet her at all. By the way, there was a senior waitress who knows the girl I like, and they talked about me. The waitress come to told me that girl "lost my number and she will come again on Saturday".

Due to that Saturday I would be very busy all day, so I went to Mcdonald's very early in the morning that she didn't come yet. I decided to leave a letter(small paper with envelop) to another worker there, to give it to her. The message I wrote inside, was like "since I didn't see you again after the first time, and you told that you lost my number, therefore I gave you my number officially this time, call or text to let me know if you aren't single, because I'm not interested in girls who aren't single." (plus some cocky&funny style in the message).

Now it's four days already and she didn't call (or didn't receive my letter, idk).
I could feel signs of interest while talking to her at first impression, her response is pretty good.
She's the same age as me, 22.
I was calm and good-looking(casual), and i was with a friend of mine at first, ordering cups of coffee.
She's quite-good-looking and looks very feminine (small and cute, not too beautiful)
I'm sure that she's comfortable while talking to me,
maybe she just don't know me and she's not a flirty kind of girl, she may think "too soon for number".

Anyway, this upcoming Saturday I will go to have some coffee at Mcdonald's again as regularly I do as one of my hobbies. I'm always playful and flexible. And i have an appropriate self-confidence.
So, if I met her this time (would be the 2nd time we met each other),
I will talk a bit and at the end I will ask like "Do you remember your own number this time? *smile*"

is it ok? overall, what do you think?
any ideas/recommendations would be so appreciated.. Thanks in advance!
she's not that kind of hot girl, -- i mean i'm better looking than her.. if u know what I mean.

sometimes it's kinda hard to anticipate, even the first impression was so perfect and the instinct told that she's into me.

idk, she may not yet received my letter, otherwise she doesn't want to call me for some reasons..
do you girls think it's possible that she gave me a subtle signal that is like "she wants me to come to meet her again and lemme try to ask for her number again" ?

Well its their job to be polite so...yeah and you should ease the cockiness a bit. Just give it time.

I would go in there and act like it hasn't been all you've been thinking about. Some girls like to take advantage of guys like you. But there's alwaysthe possibilities that she either has a boyfriend, or is trying to play the whole "hard to get" thing.

Coming from a girl who isn't too flirty, she could really be into you, but too shy/afraid to do anything. I liked a guy once and he tried to sit by me every time we had class. I was just so nervous that if he didn't sit by me, I wouldn't say anything to him afterwards~ but I wanted to so SO bad! I like your game plan. I think of she says she forgot her phone number and takes yours, then that is the best you can do, and hope for the best. If it doesn't end up working out, hey, at least you got a coffee! Best of luck!

Thanks for answering my question, I'll return the favor. I am quite shy with guys and I like to be pursued and not to give much away at first. In spite of this, in a situation like this where the guy approaches and we talk, he asks for my number and shows interest I would have called him back, especially if he came back the second time to give again his number. As a girl, maybe I wouldn't call to see if the guy is really interested and came back to see me. But after you came back the second time and you came early just to see her, and wrote a note, well, that's quite impressive to me, and makes me want to give this guy a chance, if I like him a little. If a guy was a stranger that left a note with number and was gone I wouldn't call him, but in this case you talked to her, you were friendly and polite, and you came back for her the second time and left again your number. I guess this is what a girl like me would really expect from a guy, a guy that shows interest and is able to approach and pursue a girl. I don't know if she really lost your number the first time. I wouldn't have lost the number of a guy I like, but it can happen. There could be other reasons, but it doesn't look like she is that interested after the second time. You may talk to her and ask her if there is any reason she didn't call you back, and ask her to go out with you and say that you are interested in getting to know her, and see what she says and does. I hope it helped. Good luck.
