Me and my ex-wife have two children together (9yr old daughter & 5 yr old son). In June/July 2020 she took me to court

Customer: Me and my ex-wife have two children together (9yr old daughter & 5 yr old son). In June/July 2020 she took me to court accusing me of being an abuser. Her accusations did not have any evidence and I was awarded the children's primary residence. We had joint custody but with primary residence with me. Every other week the kids were to visit their mother's from Friday 10am-Sunday 5pm. The kids are homeschooled. Between Sept 2020 - Feb 2022, she made petitions and motions to have that order changed. Each time her motions were dismissed because of lack of evidence. She made another petition and motion in the past few months. Again accusing that the kids are abused and mistreated under my care. The kids are homeschooled and she made allegations that their education isn't being take care of properly. Anyway there was trial set for Dec 29th 2022. I had everything prepared and all the evidences ready to show that everything she was saying was false and the kids themselves are happy with the set up that's been in place since Sept 2020. I was never given a chance to defend myself as the Defendant. I walked in...her attorney and my attorney talked about a deal...my attorney told me apparently the Judge was going to change things to 1 week with me and 1 week with their mom. So either I take that or the best that can happen is 2 weeks on and 2 weeks off. I was really confused where all this was coming from. My attorney never told me there would be offers made. Even when we spoke the night before, she did not tell me anything other than advise on how to be prepared for the trial. No trial occured. And I lost my days with my kids. On Thursday Dec 29, it was ordered that it will be "shared residence" for the children with 2 weeks with dad and 2 weeks with mom.
JA: Has a petition to modify custody been filed?
Customer: By who?
JA: What is the basis for the custody modification?
Customer: Mother of children alleged that kids are mistreated and not educated properly with me. But I though there would be trial and the burden of proof would be on her to prove why kids should lose primary residence with me. That did not happen
JA: Is there anything else the Lawyer should know before I connect you? Rest assured that they'll be able to help you.
Customer: That is the overall situation, but ofcourse little details here and there can be mentioned later. But this is the main issue.
