Hey guys.
I am a guy with not much of experience with romance, and I need help.

I have known this girl for about 6 months now, and we got close and "hung out" as time passed on. We make jokes a lot and I feel really comfortable when I am around her. I only thought her as a friend but someday my feelings towards her began to develope. Everytime I "hang out" with her I keep finding very good qualities that she possesses. She perfectly matches the descriptions of the girl I was dreaming to meet. We have had a few "events" (like the ones in Japanese dating simulation games) and I got attracted to her more and more. I never want to let go of her.

Now, here is the problem. She is currently in a relationship. Sometimes she mentions of her boyfriend when we "hang out," and that brings me down significantly, even though I do not mention it. One day, she explicitly asked me if I like her, and I said yes. Then she again asked if I like her as a friend. I kind of hesitated and replied "maybe" just because it wasn't the right time and right place to confirm my feelings toward her.

Do you think she is just seeing me as a good friend? I know I've got some hints and feelings that she likes me also, but I want to be careful because I might be interfering with her relationship with her boyfriend. Or am I just being used as a "toy?"
