<human>: So this girl I met through a friend and i have been talking and getting to know each other better for the past three months or so. We talk all day, we just clicked, were instantly comfortable with each other. She's been in a relationship for six and would always talk about how much she loves him and whatnot. We started off as friends and still are. We've always been fairly flirty and have a lot in common, i enjoy talking to her and getting to know her better.
Recently she conveyed her feelings to me, saying "Sometimes i feel closer to you than i feel to my own boyfriend, and i hate that. I love (said boyfriend), I've been with him for more than half a year now, and in all this time you're the first person that's ever made me doubt my devotion to him. Don't let me stray from him, remind me to be happy with what i have." She says it's overwhelming at times.
I'm not trying to get between their relationship at all, he's a nice guy that treats her well and I'm happy for her. I do have feelings for her, but I'm not chasing after her or anything. I want to be whatever she needs me to be, which right now is a friend. She's become a huge part of my life. She's my best friend, I care about her, and want her to be happy. And whether it's as a friend or girlfriend, I truly want her in my life. 

What do you ladies think that she's feeling right now? What should i do about it? Am i doing anything wrong?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Girl tells me that a lot of the time she feels closer to me than her own boyfriend. What does that mean? And what should I do?
