Help Juan Ortiz get custody of his son

About 8 months ago, me and my ex split up shortly after having a child on November 1st, 2016.
Since then, she's caused countless problems for me, but I've always had my son living with me through it all. She's stolen from the government, neglected her son in multiple ways including not offering any kind of financial support for his necessities in the past year aside from an occasional bag containing 7-10 baby foods, or a pack of diapers here or there. Now that he is starting to walk and talk, she wants to come back into his life - by having him live with her. In the past she's asked about moving back to her home state of PA, knowing that I'd be unable to make the trips to visit him, or see him. She's threatened me with having my parental rights stripped even though I've done nothing to cause this to happen. She was emotionally absuive, controlling, and narcissitic all of the time when we were together. I've done it all for him; late night feedings and diapers, day time feedings and changes, baths, dressing him, all of it since he was born. When i worked a 12AM to 8 AM job, I only got 3-4 hours of sleep a day - if she allowed it - due to having to take care of the baby. She's taken him hours away out of state, in 30 degree whether while he was sick, broken his routine and schedule countless times, and has very little stability in her personal life. I know living with her would have terrible, negative repercussions on my sons physical, if not, mental health, especially when he starts school. She's constantly insulting me and my family, belittling us every step of the way.
I put in custody papers in court recently, and would like the courts to see that it isn't just me that believes his health and well being would be better off in my hands, and not a neglectful woman who decides to be a parent once the "hard part" is over.

Now, don't get me wrong; I know I'm not perfect. I have my mistakes when it comes to the baby as every first time parent does. But this boy has actually saved me from myself if that makes sense. Before I knew about him I was reckless and on a road heading down self destruction. I've sacraficed countless hours of sleep, and more friends and family members than I can count for his happiness and health. I've dedicated my life to giving the baby the father that I wanted when I was growing up. I recognised my mistake, and instead of running away from it, I decided to own up to him and play the role I need to. After all, he didn't ask to be born; so why should the people responsible for him existing make his life difficult? I didn't want to be a dad this early in my life, but that didn't (and still does not) matter. I taught him his first word, which was "Dada". His first steps were across my living room towards me. When her was in the hospital after being born, he held each one of my index fingers in reach hand, and I promised him I wouldn't leave his side ever, and that I'd make his life as good as I possibly can no matter the cost, consequence to myself, or situation. I've used that promise as a guideline for my entire life, ever since I made it on November 2nd, 2016 at 3 o clock in the morning. 

By signing this, you are stating that you believe the child Juan Ismael Ortiz-Cruz is better off with me getting full custody. Thank you.
