If committed guys are always attracted to you, it's really not your fault.
They are committed, meaning they are experienced, and they usually think you are easy to lure, easy to catch. It happened to me, akala siguro ni guy officemate e papatulan ko siya, I was very young then, and he thought I was innocent and too naive.
Anyways, it seems there are 2 situations here:
1 - Girls getting attracted to committed guys, for no reason
(if wala ginagawa yung guy sayo, then you have the problem, try to control yourself or ypu will get hurt afterwards, mahirap me kahati)
2 - Committed guys trying to attract girls like you
(don't give in to their traps, be wise, they just want some fun and take advantage of your loneliness)
