Soon to be single mother of 4 children

Hi my name is Gloria and I have recently been faced with being a single mother of 4 children. I have 2 handsome boys, 5 months old and 3 years and I also have 2 beautiful and loving girls that are 11 and 17 years old. I have always been a devoted mother and wife. I have not always been perfect but to this day I have not met that perfect person yet. We have been together over 20 years and married for 14 of those years and I did everything for my family. I worked 2 jobs as an RN, mainly the night shift, sometimes working 60+ hours a week to support my family because I was helping my husband through school to better our future. I have always been a hard worker so it really didn't bother me. The only draw back to the long hours was not being able to be with my family but I was doing this for our future, so I thought? Well I guess my husband decided to change his plans 2 weeks after I had my last son. He decided he wasn't happy anymore and wanted to separate and now divorce.  I noticed we started to have problems when my husbands parents moved out by us and did nothing but baby him. This was an issue for us in our past and that's why we moved away from them 7 years ago, unfortunately it once again is an issue. There was also something else that happened while I was pregnant with our last child. I confronted him about it but he denied it. I won't get into the details about that but I'll just leave it to your imagination. I have received no financial support from him either throughout this whole situation. I have no family where I live and have basically been working and taking care of my kids by myself while he lives his newly regressed single life. I am struggling financially and cannot afford to pay for an attorney, as you all of us know attorney's are not cheap. I normally do not ask for help for anything but I am so alone and am hoping that family, friends and even strangers may be willing to help. This is not an easy thing to do but I want to protect my kids and myself. I hope you will find it in your heart to help, thank you in advance for even taking the time to read this!
