<human>: Can you succinctly summarize the text in 1-3 sentences?

There is this girl that I've had the hugest attraction for the longest time. When I asked her out she politely refused but I still haven't backed down yet.

I'm wondering were to draw the line when pursuing someone? If people gave up after a first attempt of refusal or initial sign of disinterest then some people wouldn't be here today. For example my grandad kept getting rejected by my grandmother for about a year before she finally said yes to going out with him.

I just don't want to come across as creepy but I wouldn't be doing it if I didn't feel really strongly about her. I'm not sure what to do. Any advice?
<bot>: girl I liked doesn't want to go out on date after I asked her. I still want to pursue her but up to what point is it acceptable?
