But its not the fact that i was the side bitch ... me & this boy use to fw eachother when school started kissing & spending time at each others house nd all we was close . We fell out ,he got a gf ,me nd him started messing around again ... but i feel like he use me .. he dont got a job or nothing but i take care of him .. i buy him ubers to get places cause he said he be stuck & i feel bad , i bought him food & errings, all dat. Im sadly inlove with him nd he in love with me nd his gf or bae or watever she is . Im hurt by the fact im being used but idont kno wat to do with him like im 16 nd suppose to be living but im strugglingg‼‼
