Who should be my TRUSTED best friend...??

Well here's the fact.... There are two girls whom I love very much n the other loves ME very much. But the one I love meer is kinda weird. Like, she acts like I don't even exist. She keeps ignoring me. We have MANY histories of past. Many things happened between us. And the other one helped me a lot with those. But the one I love more, doesn't give a shit. Well its not like she doesn't care. She does. Her inner actions say that she loves me. She always remembers my birth date. But the way she acts, it feels like she hates me. Well whatever on the other hand, the one who helped me, really expresses her feelings for me. So, help me guys, who should be my BFF?
