Should take my ex husband to small claims court?

[blaeey]

I just divorced my ex husband. We had 2,000 dollars in debt together. Our names were on each account. He agreed to pay me half. I paid the 2,000 but now that I paid the debt then he says he isn't paying his half. I even gave him the option to pay me 200 a month until the debt was paid to me. I have two young children and I am trying to start over its not fair for him to do that to me or our children. Should I take him to court? I paid all the debt at once so I can have my own place when the landlord checked my credit. I left him.
