<human>: I'd first like to say that my girlfriend is not a lesbian nor bi. She is just more publicly intimate with her best friend rather than I, her boyfriend. 

We have been dating for 2 months now, and we have been quite alright except for the fact she sometimes seems upset when I point out I have an attention competition for her with her bestfriend. The worst part is that her best friend usually wins, making my girlfriend link arms with her instead of holding my hand. 

My girlfriend has been best friends with her for about 11 years now, but she likes to rant about her best friend and how she ruins relationships and friendships that intrude their friendship time; at the beginning of this relationship, my girlfriend actively tried to keep me from talking to her. She tells me that she's just being there for her best friend who is going through a lot, but even when neither of them seem trouble, my girlfriend picks her over me. I feel like this is a huge wall in the way keeping my intimacy with her from reaching any other level passed making out and cuddling. 

I'm well aware that they have been friends for a very long time, but the last time her best friend had a boyfriend, she'd just ditch my girlfriend for him never to be seen again. I personally feel that my girlfriend just doesnt know how to detach from her, even though she has thought about doing so many times. Oh yeah, sometimes her best friend treats her like complete shit.

Can you condense the text into three sentences or less?
<bot>: my girlfriend of 2 months seems to be more intimate with her best friend of 11 years rather than me, especially when all three of us are in the same room.
