i need advise

Hi po attorney...I've been married for more than 12years now but now I decided to separate from husband. Since we started living together yung family nya n po ang nag susuport sa amin. Within 4years n pagsasama namin wala syang work so lahat ng mga kailangan namin provided ng magulang. We have twins and currently po they are staying with their grandparents since yung school n pinapasukan nila mas mlapit sa mga in laws ko. My problem with my husband started po ng magkaroon n sya ng work. I found out po yung first affair nyo through his cellphone and eventually hiniwalayan nya rin ung girl. Akala ko tumigil n sya sa pambabae nya pero nasundan p po un ng ilang beses at ibat ibang babae at umabot p so point na iniwan nya kami. Umpisa po ng mag work ung husband ko never po akong humawak ng sahod nya. Yung present nya babae ngayon ay dinala nya sa bahay namin while I was at work. hanggahng sa kinausap n namin yung babae but until now they don't stop seeing each other. Since he started sa pambabae he always blames me for what he did and even degraded me. His parents knew all of this but they are just their to mediate pero wala rin pong nangyayari. I wanted to be separated with him legally. Anu po bang grounds ang pwede ko i file?

Good afternoon attorney ask lang po ako ng advice, separate na po ako sa husband ko ng 8 years may boyfriend na po ako ngayun at gusto na po naming magpakasal pwede na po ba akong magpakasal ulit. wala na po kaming communication nung first husband ko since nung magkahiwalay kami at hindi ko na po alam kung saan na sya ngayun. ano po ba yung pwede kong gawin. Thank you!
