Harassment?

What is the name of your state?North Carolina
My husband has 2 kids from his previous marriage,10 and 8. In July he got hurt on the job. We kept up with the child support payments ($500) with his Workers Comp. check. When he finally got back to work in Oct., he was not given back his second job,(usually $4000 a month) which is where most of his money came from. From his 40 hr work week he only makes $350 a week compared to before where it was $1200 a week.We fell behind in Nov.. We filed bankruptcy at the end of Nov. due to him not having his second job. She has called saying that since he is not taking care of his kids, she will call an attorney and get him thrown in jail for not compling with the child support order (which was one they agreed on together, not a court ordered one). She calls him and tells him if she can't make a bill its all his fault.( She has a good job working in a doctors office) She tells their kids that daddy's not taking care of them and sometimes even uses them as a go-between asking my husband for money. She called him at work today to tell him her car got repossed and its all his fault. Is this harassment?? Can we do anything about this?
