Ex Wife Has Moved My Minor Son From Her Home To A Whole Different State!!aaghhhh!!

???? with me folks...this is my first post on reddit I am a 42m who lives just outside Atlanta GA(Roswell to be exact) and I have a 42f ex wife that resides in Colorado Springs, CO with my 15yr old son. We were divorced here in ga in 2013. The following year she decided to move to Jacksonville FL with my son. They did. She began a relationship, got married and had 2 little girls. The entire time she lived in FL, she refused to meet me halfway for pick up and drop offs. So me, being me, was the one that would drive from Atlanta, to Jacksonville..pick him up(while he was waiting at the curb by himself) turn around and drive back. 17 hours. Everytime. For years. Then she decides to move to Colorado. Things go ok for a little bit but he begins to tell me on his flights out to me that his stepdad is being a bit abusive. He is around 12 at this time(right as covid hit). I have no money for a lawyer, my wife is on her literal deathbed at the hospital because of a feverish Cushions Syndrome, and flights can't be taken because of covid. Fast forward to now because this has already gotten to long... My ex wife tells me 6 months ago that my son is going to go to West Virginia to visit his grandfather because he just had some type of surgery and may need help around the house for a couple weeks before school starts. When I inquire a little more, she tells me that her mother is living with her in CO. Next thing I know,she enrolls my son in school in WV without telling me. When I call the school, they have no idea who I am. I have to email them records proving that I am the father and everything. She tells me that he will only be there for the first semester to work on his grades. He is failing all his core classes!! He is still out there! I have been emailing her, calling her, texting her, for months with no responses. My son has me blocked. His grandfather won't respond either. I am at a loss!! I have never missed a payment or a call or anything from the time we got divorced. I know this is a multi-state issue with lots of ins and outs but I am going crazy!! Any advice would be soooooooo helpful. Please!!!!!! Thank you so much!!!!
