Ok so I have a huge crush on my friend. We're both girls. She is openly bisexual and as far as everyone knows I'm straight. Sometimes I think she might be flirting with me but she keep sending me mixed signals. She's been have problems with her girlfriend and said about a week ago that they are "official" done for good. But idk for sure. I've caught her starring at me a couple times and then she'll smile and look away. And when we sit near each other and our arm or legs or whatever touch she doesn't move she just stays there right up next to me. She is also a big conversationalist around a group of friends but when it's just me and her she doesn't say much and niether do I cuz I'm get nervous around her. Idk if she is shy or not. This has been going on for about a month between us. Idk if she if she I trying to figure out if I'm gay/bi or if she is really hitting on me at all. What should I do? Idk how to flirt and I'm somewhat shy. Please help!!
