Cannot see my children

I split with my ex partner 12months ago. it was my decision to go, but i felt at the time it was right and i now know it is the right decision i made. My only mistake was not to do it sooner.The problem is that now my ex wont let me see my children. When we split all i wanted was the best for my children, so i gave away my share in the house(£70,000 equity) so i knew my children would be brought up in a good area, in a good sized home.

I gave my ex £700 pounds(3/4 of my wages) for the first 4 months so i knew all bills would be paid and children would not want for nothing.I got to see the children every 2 weeks which i argued it should be more but she said it was that or nothing. i pay maintenance on the dot every month. Then my ex decided she wanted more, when i refused she stopped me seeing children. She contacted the CSA who then informed me i was paying too much!! Now i have not seen my children since Jan 22 it is now early june.

Her response now is to go to court so i will have to pay thousands and she going to laugh in my face and ignore the first order.(i will skin you!!!) i have been to solicitors and had letters sent to her but to no avail, i cannot get legal aid and i cannot afford to go to court. I am at wits end, people tell me to stop paying her money every month but i want to provide for my children but i WANT to see them!
