<human>: Give me the gist of the text in a nutshell

There's this girl I really thought I got over, but recently realised it was not the case, as we started talking again, and went out once. We click on all bases, mentally speaking. Here comes my problem. 

Her birthday is coming in less than a week. We might or might not be in the same city. My request, if you would, could you please share the birthday message that gave you the most emotion, gave you that sweet smile. I've been looking for it inside, but my head is a mess, I know I won't be able to get out exactly what's in my mind. If by chance, we happen to be in the same town, do you have any suggestions about what might be a small, significant gift( I'm on a student's budget unfortunately...).

Thank you all for your time and answers. Sorry for the bad  formatting, I'm on mobile.
