I have been supporting my ex-wife after she lost her job, it has been a year still no job. AITAH for wanting to request full custody of our children?

Throwaway account for obvious reasons.

My ex and I have been divorced for six years, we have two children together 8 and 10. We have joint legal and physical custody we have been doing week on and week off for four years at her request. Prior she had them only for the weekends while she figured some personal stuff out which played a factor in us getting divorced.

Last June she was let go from her teaching job due to budget cuts, since I did not want to take her time away from our kids away i did agree to cover all her expenses while she got back to her feet. It has been over a year and no update on the job front. Yes, this is ontop of my child support payments because of the difference in esrned income. In CS I pay around 250 per child per week. I don't have an issue making payments if she was actively trying to find a job.

Last conversation we had she was doing user generated content and working on establishing her brand. ​With the occasional grubhub, Uber eats, and doordash order. This where things get murky for me, and need a different perspective if my view is overly critical or harsh. She recently has been bringing our childern with her when she does her deliveries and posts then on social to help establish her brand as a go getter mom. They are mostly harmless in terms of content. She provides tips, tricks, and support for single parents especially mothers. I don't feel comfortable with our children being in that environment any longer.

Now, that it has been over a year I am considering seeking adjustments to be made. I spoke to my parents but they are the type that don't think people should divorce and we should get back together. I am single with no real interest in finding or dating another person. We did get divorced for what I feel is a valid reason and will nor disclose that here but if I do ask her to move back in or get together she probably would say yes. Just don't think I can go back to that.

Looking for some guidance here.
