filed me a slander case..pls help

I am a private employee, 25 yrs old. My problem is that my neighbor filed me a case for slander daw. Nag kalat daw aq ng tsismis for her daughter na nabuntis daw at ng palaglag. That's not true, im only asking her boyfriend na totoo ba ang nrinig ko na ngkaroon daw xa ng problema kung paano mgpalaglag?(kasi nrinig ko po sa cousin ko na his asking daw to my cousin kung paano mg palaglag).I'll never mentioned naman na it was her girlfriend. Ngayon ang nkarating sa kanila is ako daw ang ngpakalat ng tsismis na ang kanyang anak ay nabuntis at ngpalag2.Ng punta na po kami sa bahay ng capitan namin, it was proved that hindi talaga ung girlfriend nya ang tinukoy na ngpalaglag its was his ex-girlfriend and also it was a joke. Two days after i received an invitation letter from the brgy stating that i have to answered the case filed by her father. Then the brgy give them a certificate to file action kasi wala pong witness na nkarating sa brgy. Ipa2rating daw nila ito sa korte...ang liit2 po kasi ung issue so may mga tanong po ako;

1. Makaka file po ba sila ng case against me?
2. anong case po?
3. malaki po ba ang evidence nila eh kami lng po ng boyfriend nya ung ng uusap. tinanong ko lang if totoo ba ung narinig ko na ng karoon daw sa ng problema kung paano mg palag2?
4. Makakafile po ba ako ng case against them kasi nrinig ng nanay ko na ung statement ng nanay ng girl na"ung mga tsismosa ay dapat ihulog sa bangin! at kung wala ng pangastos sa kaso eh patayin na lng para matapos?."

looking forward for you reply..thanks
