I don't think the last part is desperate at all. It's just being nice. This guy is a jerk. You seem nice. If you are having strong feelings for him early on, just take a quick step back and take a breather and realize you're probably just a person who gets invested emotionally pretty easily. I'm confused how the first situation was a situation of desperation as well, but if you said something to him that was a bit much perhaps he could have been put off (being a first kiss etc). Still, seems like a jerk to me (I'd just be flattered and take it into account if you did say something that might be construed as a bit much for a first kiss and either end it with you and run with whatever it was you said, for the record, and I consider myself not such a jerk, although I am a bit biased). You can do better.
