long distance relationship

I have been in a long distance relationship for 9 months. he lives in Paris. I live in San Diego. I am the one who always commute to france as he can’t move right now as he is just divorced and have 4 kids in custody.
I have 2 but I am in good term with my ex so I have flexible custody.
I manage to go to france every month and stay one week. we can manage this relashionship because he is working for himself and can manage his afternoon for me when I am there and one week end.
Problem: He decided to look for a full time job for more security. knowing that we will not be able to see each other again during afternoon and neither at night because he has his kids. so only availability will be during week end. He knows that it will destroy our relashionship as I am not going to commute 11h flight just for one week end per month. I am fed up doing all the work to make it work.
I feel angry. what do you think? I am lost. what should I do? thanks
