why do you care what a bunch of randoms on the internet think about you going after a girl with a boyfriend? fair enough asking for advice,but who cares if anyone thinks its a bad idea,ive done it once before,the guy turned out to mistreat her and act like a wanker (never see her,not care much etc etc),and i gave her the attention she wanted,she *****ed about him and i simply filled in the gaps he wasnt,me and her got close and this guy didnt even know who i was,he dumped her she was sad.. he didnt care at all,then 2 weeks later me and her started going out,she broke up with me for unbeknown reasons just 2 weeks later,and now she is the biggest ****block and i wish i never dated her
