Mutual out of court settlement/ live in relationship for over 10 yrs with children

This is a second marriage kind of for us both though not legally married yet live in under the same roof last 10 yrs approx and i have a son from my first marriage and a daughter from my second relationship taken care of by my second so called husband who has been pretty abusive and intolerant and i have been a victim of domestic violence which i have tolerated enough as he was always into alcohol and tobacco and exploited me to the brim since i was neither financially nor career wise as sound and strong as him. Now he is transferred to a different state and keeps no contact despite several calls and wassapps from my end until i gave him a stiner message two days back as my daughter was suffering from too much ill health and he didnt respond to so many calls though had time to update posts on fb and smule. As a revert to my stinker message he blocked me on his fb and wassapp and tele calls, i need justice. I want separation without dragging coz i dont hae enough money to keep dragging cases ; i need money for the upbringing and education of my 8 yr old daughter if not for my son and i dont want any alimony as that will only make the case drag to its worst. Please help.
