<human>: Can you give me the gist of the text in a nutshell?

So here's the situation. This girl is my best friend. There is instantly a connection when we hangout and have known each other for just over a month. I have feelings for my best friend, let's call her sam, and she has feelings for me as well. She's everything you could ask for in a girl, beautiful, sweet, smart, understand, very funny, etc etc. 

Here's the problem. She is very close with my ex of a year and a half, and she's scared of her reaction if we get together. She's scared of losing her which I totally understand, and neither of us know what to do in this situation. 

Any help is appreciated, thank you.
