In need of help for a Family Attorney

Hi, my name is Derrius Loving. I'm creating this GoFundMe because my son is being wrongfully withheld from me by his mother since I've gotten into a relationship after we both mutually ended things on 9/12/2022. Today is 3/6/2024 and the last time I spent time with my son was 1/10/2024. First thing I want to make known is that I've been an active great father since my son was born. Having him withheld from me for no reason and not being able to consistently be a father to my son is tearing me apart and I'm asking for you all's help so my son and I can reunite and continue the bond we share. Before getting into a relationship, the mother and I strictly co-parented and did a well job at it. I was able to get my son whenever I wanted to and spend unlimited time with him before dropping him back off to his mother. I've been in a relationship for a year now and she's been consistently making it difficult for me to spend time and see my son ever since. Every family attorney I've reached out to is 3500 and up which is difficult for me to come up with at this time considering daily life expenses. Any help will do. Thank you all so much in advance!
