my ex was given full authority of our kids when we separated on the grounds that I couldnt bear the cost of an attorney and she had the option to have her bf pay for hers.

my ex was given full authority of our kids when we separated on the grounds that I couldnt bear the cost of an attorney and she had the option to have her bf pay for hers.
she has total control,that implies where,when what time or regardless of whether I can see or converse with my children .I was having the option to see my children two times every month and converse with them 3 times each week.
her bf and I got into a contention and in light of that she said I cannot converse with nor see my children again until I can get an appointed authority to make her let me......im going through dissability and cant manage a lawyer,what would I be able to do to get contact with my kids,ive asked and pleaded,i havent seen them since thanksgiving 2020.any assistance is valued.
