<human>: My friend [27 M] has been dating this girl for about a year now. She used to live far away so I never really gotten to know her. But she recently moved in with him so we all have started hanging out. 

He left a couple weeks ago on a 2 month business trip and he suggested that I introduce her to a TV show that him and I watch. I started this off with no ill intentions at all, but she has a 2 year old so we inevitability just sit there talking while the kid falls asleep. I have come to find out that we have just about everything in common. She has even told me she can be herself around me when she can't around my friend. And I am usually super awkward around women, but perfectly comfortable around her.

I really don't want to jeopardize my friendship with my friend since he is one of the few people I still hang out with. And the others are basically his brothers. But I like this girl more than I have liked any others in a long time. 

So I need unbiased opinions. Am I a scumbag? Should I tell her? Should I remove these feelings before they become anything more?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Tell a girl how I feel, possibly (probably?) losing all my friends? Or bottle that shit up (again)?
