<human>: Summarize the given text in a few sentences.

Here is the story. 
I knew that she existed for about a year (haha), but we met on a party I threw two months ago. 
I told my friend to come to my party and bring the girl too. At the party, we talked few times and I think she had fun talking with me (maby because she was a little bit drunk, haha). 
Then party ended and we never met IRL again. I chatted her a few times on Facebook, but she didn't reply so often.
I mean she always did reply , but after 5min, 15 min or even few hours... 
She always replies kindly, but I think she doesn't like me that much. 
Maby because I'm not that handsome or I don't have that much social skills, haha. 
Sometimes I saw the "Seen [...]" thing on Messenger and no reply for hours. 
The question is : should I try or should I pass? She's single and she's never been in a relationship.
<bot>: She answers rarely (after 5,15min or even few hours) and I think she doesn't like me. Should I pass?
