Should i drop my best friend?

Im not saying you need to drop her as a friend. But it sounds like she's way too into herself. And people like her case have low self esteem thats why they talk about theirselves and lives 24/7 without initiating conversation about yours or changing the subject to them when your trying to talk about you. You need to talk to her about how she always makes everything about her and never about you. And that you cant stand it. Tell her you love her but this all about me attitudes gotta stop. If she gets upset ect then say how would you feel if i acted like that all the time. Try talking to her about things before "breaking up" and if that continues to still go on keep her in check and make it into something funny so she wont get so offended for instance if she keeps going on and on about herself, start singing ridiculously that country song called wanna talk about me by trace adkins, the chorus should give her the point" i wanna talk about me wanna talk about i wanna talk about number one on my me my what i think what i like what i see i like talking about you you you usually but occasionally i wanna talk about meeeee..""""" lol anyways hope that helps. If she just doesnt stop then in the end you will grow apart. LUCK!
