i've never had a bf before. its not that no one has approached me before, its just that whenever i start to like someone, once i become really close with him (or enter that MU [mutual understanding] stage0 i start to lose interest in him. i'm such a jerk!

i really hate this part of me. i really dont know what to do with myself

i just recently did this to a guy again! he's a new guy at school and i started to like him the first time i saw him. we didnt really have any classes together, or similar friends but that didnt stop me from approaching him and talking to him first. and then somehow, we became close friends and then we became MU.

once again, i lost interest and stopped liking him. i used to always be excited to see him, and i was always the first to notice that he's around. i always used to call him out too. but now, i don't feel anything for him at all so i feel guilty and avoid him. i don't want to play with his feelings so i think its a good idea to try to distance myself from him so as to not to give him any false hope. but im really terrified of how well i can act like nothing really happened between us.. im aware that this is hurting him, so i feel really really awful about myself..
i feel like such a player; the enemy of all men and i don't know what to do. im scared that i 'll be hurting more guys in the future.. and that this will somehow come back to haunt me or that they might try to get back at me.. whats worse is that i start getting interested again and become jealous whenever that guy all of a sudden moves on to another girl..
ive done this to so many guys already

i feel so guilty and it hurts me inside whenever i see the guys ive done this to.. i know that i'm such a shameless person and that i shouldn't chase after guys when i know that this is going to happen but then i really cant really stop myself from losing interest the same way that i cant stop myself from liking them

you guys are prolly hating on me now

but pleasee help mee! what should i do?
