I have another option... tell BM that you are willing to allow her liberal visitation, however, you want her to agree to terminate DH's child support (she should not be getting CS if you and DH are providing for all the kids needs), and because of the fact that the kids are now in a stable home and under yours and DH's supervision were able to keep SS from being held back and are the ones who have gotten them dental care and all that jazz, you want primary custody of the children, and until she has proper housing for the children (a 2/3 bedroom apartment or the like), she only takes the kids for evenings and EOWE, once she has proper housing, you are willing to agree to EOWE and one or two overnights a week with her bringing the kids back to your house for school (if at any point she stops getting the kids to your house on time for school, her week night overnights will immeadiately stop and go to weekly dinners only). If she consistantly does so for the rest of the school year, then week on week off would be an agreeable arrangement when summer starts/ends, assuming she has a reasonable commute to get the kids back to your area for school. And you want it all in writing and signed off on by a judge.
If she is unwilling to do so, then tell her you are prepared to take it before a judge that two school aged children of opposite genders are going to be living in a one room unfinished basement with their mother, who failed to get them to the dentist, didn't know what doctor to contact for shot records, willingly handed the kids over to their father when she broke up with her boyfriend because she had no job or place to live while the father paid for ALL expenses and she has been CONTINUEING to receive child support for children she did not have in her custody. This will all look bad on her with any reasonable judge (especially if your state has issues with opposite genders sharing rooms) and might scare her into giving you what you want. Just make sure you are documenting that he is still paying child support while you are still paying for all the other expenses and receiving no help from BM and the kids are enrolled in YOUR school district.
