abandoned wife

I married a man I've met through internet po ..Today is supposed to be our 8 months wedding anniversary. Hindi talaga kami nagsama ng matagal kasi 3 days after wedding nmin bumalik na siya. He is in US now a US citizen . We had a fight that he chose to leave me and not to communicate with me. He changed his number po and I could only reach him through his email. Despite all my messages for a month he doesnt response to me anymore. I dont know where he is now or what he is doing.. Gusto ko sanang malaman kung anung pwede kung gawin para mapawalang bisa yung kasal namin. Pwede ba siyang mag file ng divorce dun para mkpag asawa kmi pareho? Tsaka withdrawn na rin niya petition ko to go to US. Maysakit din pala siyang PTSD sinabi niya sa akin pero hindi ko alam ganun po pala kalala.... Nakaka apekto po talaga sa amin kasi long distance na nga po relationship namin kunting pagkakamali ko sobrang galit n po niya sa akin at heto nga ung last gumawa po siya ng decision na sobrang nasaktan po ako kasi mahal ko. Pero wala nman po kming anak... natatakot din po ako security ko bk dahil sa sakit niya makarating man po ako US e bk mapatay niya ako. Sana mabigyan nyo ako ng advice kung anung pwede kung gawin po
