What should I do about stepdaughters mom?

I think your husband should fight for custody.She seems like a head and very jealous of you.If he's doing everything he supposed to doing then she should let him see her.Did the court order him to pay support?If so then he should be able to see her no matter who he's with.Does he have dirt on her if so tell him to fight for custody.And i think he has dirt on her like all the times you guys did keep her.Did her mother ever call to check on her when she was with you guys?If i was you i would start writing everything down this means when you guys did keep her for 2 years write how she just left her like that and didn't want anything to do with her.Make sure your husband calls every night to check on her even if he don't get to talk to her write it down the time,date and how long they talked on the phone or if he even got to talk to her.When you guys go back to court take everything you have wrote to show the judge or read some of the stuff you have wrote to the judge.If your husband has a lawyer he can use what you write down in court that way he has an idea of whats going on.Just keep your head up and keep fighting never give up and forget about the mother she's just doing what she's doing because she's jealous of what you and your husband have.I hope things get better good luck to you both and remember to write everything down believe me it helps out a lot i went through the same stuff with my sister i had to write things down for her,because she's slow and didn't know what to write.I wish you guys the best.
