<human>: My best friend recently moved to Florida 

and his sister moved down from DC to 

be closer to family. Until she moved 

down we had met a few time and I never 

thought of her as more than a friend. 

When he moved away and she moved 

into his place he wanted me to show her 

around town, cool places to hang out, in 

general keep her from feeling completely

 alone in a new town. We've been out 

and went to party's on multiple 

occasions as friends and spend at least 

one day over the weekend together 

every week. It wasn't until recently that I 

found myself thinking about her the

 majority of my day.

I guess what I am getting at is my best 

friend and I had a mutual friend that went 

out on a few dates with his sister and to 

put it simply he hadn't been invited 

around since. I don't know of it's his 

personality that caused the problems or 

just the fact he was dating my friends 

little sister. I really like her and I'm at the 

point of not knowing where to go from 

here. This is the first time I'm been 

legitimately interested in someone in 

years.

Can you condense the text into a few key points?
<bot>: My best friended moved away and his sister moved in. I developed feelings for her I'm not sure I should have.
