The thing that i kept thinking in my mind..

What should i do if someone that i like so much before comes back when i already have a girlfriend ?

I met that girl when i was form 3. She's awesome and i was so happy being with that girl but we got into a fight and i made a statement that " maybe it's not our fate to be together " . After a while she deleted her facebook and changed her number.

 She just disappeared like dust . I never had a chance to meet her or talk to her. 

But when i'm in form 5 and i already have a girlfriend, she just showed up in front of me . I was like; is this her ? My friend told me that i still have feeling toward her . I think my friend's right but what should i do ? i already have a girlfriend but i still like that girl .. I really don't know what i should do. 

P/s : Guys if you know what i should do please tell and help me .. I really need help now .

Guys ..

Yes i know that i am not a perfect person but i'm still a human being and have feelings . Sometimes i feel so confuse with my life . I don't know what's good and what's bad for me . My life is not that happy but sometimes i have to be a hypocrite and show to people that i am happy . The reason i do that is because i don't want my parents and my friends are worry about me. 

Guys i have a question for you . What does a girlfriend really  means to you ? What good thing can they do for you ? Why it so hard to take care of your girlfriend ? They told you that not to be so close with other girls but why she can be so close with other boy ? Is it fair for the guys ?  What is the meaning of 'boyfriend' in 'girlfriend' life ? a toy ?
