2 things ✌ First thing...she doesn't want u and that's an excuse for breakup to make u feel better about ur self and go to other niggaz.. Second reason....she just loves u so much she dont want to mabelashet you or she is holding u back in some way so she get her self away from u...but mostly the first reason happens most of the time Or Maybe there is another reason who knows maybe she is just bored.... girls are complicated but there is no such thing as "its not you its me"...BULLSHIT u tell her its okay if she is a problem and u will still love her but she goes anyway so dont try just let her go if she wants to leave....
