Um okay so this guy from another school confessed to me when he had a girlfriend.

Before he confessed, he chatted me everyday, so we got really close.

We met a few times, and at last he decided to confess to me ._.

But i couldn't say no that time since we were so close..... and I didn't want to friendzone him.

So we went out 'secretly'. Basically he was cheating on the other girl 'secretly'.

His girlfriend hated me from beginning, and a week later me and the boy broke up.

And he did the stupidest thing. HE FREAKING TOLD THE GIRL THAT WE DATED.

The girl eventually got really mad at me, so she told my whole grade about it, so EVERYONE knows.

Some boys will just pretend like they don't know, and some would just tell me it's okay, everything will be fine.

But the boy that I went out with told me that the girl wasn't treating him right. 

She never chats him, makes excuses, and it pissed him so he confessed to me.

And at last he broke up with her, and he confessed to me AGAIN... so i said yes, since they broke up.

The girl is now blaming me as the reason they broke up.. what do I do? Am I a bad person??
