Please help me and my 2 sons have a new start

Hi my name is Areina im single mother of 2 sons. On february 23rd 2014 my fiance' Shane had tragically passed away in a fatal car accident. Shane had previously served in the united states navy but since we were not married at the time of his passing im not entitled to any thing and my sons werent entitled either despite helping me raise my boys since my oldest was 3 and my youngest was 4-5 months old shane was only their dad and not their biological father. Sadly their biological father isnt in the picture and refuses to be there or help care for his sons. Since shane's death we have stuggled to get back on our own and being out of work has made it even harder. About 3 months after his death i was laidoff from my job and with alot of people losing their jobs due to the casinos closing jobs are hard to come by in south jersey . I now have an oppertunity to relocate to floirda for a great job and a better life. I have 500 saved but i know it wont be enough to get us there and into a place. Sadly im on my own trying to do this so im reaching out to anyone who can help any little bit can help . Im not one who normally askes for help cause i rather help others instead if you or someone you know could help we will forever be greatful to you all. Thank you so much. One thing i didnt mention was that during the course of the last going on year my fiances father has basically terrorized me and my sons taking me back and forth to court just cause he can and nothing i have done thru the courts has gotten this man to leave me alone he is out for revenge and doesnt care how this has effected me and my sons. I had also miscarried a little boy at 14-15 weeks of pregnancy from.the stress and i dont usually put my personal business out there but someone recommend that i be as honest as i can be about the situtation. So moving will bring alot of good back into our lives. Thank you again for your time.
