## I'm either in love with my best friend's girlfriend, or I'm just discovering what it's like to be alone.

My best friend got a girlfriend about a year back. She ticks pretty much every category when it comes to what I believe is the perfect girlfriend, which makes sense that my best friend would go for her seeing as we are hella tight buds with heaps of common interests.I have never really felt alone before; I've always been able to keep entertained/comfortable. But when I see them together, I would feel sort of empty or cold (mainly in the chest). With his previous girlfriends, I would never have this feeling. This is essentially the reason why I'm confused about what I'm feeling.Now here comes the twist, recently she's been a lot more physical. She's started to be closer whenever she's near me. It started off as a shoulder to shoulder thing, but has escalated to lying on top of me (in a non sexual way). And she would also sort of curl up next to me in the space between my arm and my chest. She's hitting me with heaps of red flags here.I'm generally a positive person, and so my thoughts as to why she's being this way is because she's not getting this attention from my best friend. And so she's doing what any normal person would do, which is getting attention from another source - me (the dickhead with no backbone).I have definitely noticed a connection between the two of us, but I'm finding it difficult determining if it's a friendship thing, or something more. The whole decision on whether or not I'm feeling lonely, is really getting difficult with the way she has been acting recently. Her being near me is a great way to feel less isolated, but it's such a temporary feeling.Help the lonely boi.Edit 1: I kind of still want to be friends with her, like after whatever happens. After reading through some of the replies, most suggest ditching her. I've noticed that I feel really comfortable around her in the same way I'm comfortable with my best friend. The only difference is that I've known him for what seems like forever, and her only for a year. I genuinely believe that her and I could be bestfriends.Edit 2: I've always had that need for things I feel I can't have, and in this situation it's the desire to not be lonely. Whenever she is around me, I no longer have the feeling of being lonely. But then the feeling of guilt takes over, for the fact that she is my best friends girlfriend and I should be keeping my boundaries with her.
