Should I Go To Small Claim Court?

My ex borrowed $10k from me, and she has been paying $100 per month. I initially accepted such low payment because I knew she was financially struggling.

She got a new job and she claims she is making more than 3 times of annual salary than before. I asked her to increase the monthly payment, but she refused. She is still paying $100 per month. She even said this $10k is undocumented and told me to get a lawyer if I want to get more every month.

I have text messages of she agreed paying to money she borrowed.

Will the court help me adjust monthly payment with her?
