Divorce Support Forums: hi i need some help please

i have 4 kids,2 by my ex and 2 with my husband, 16 and7,my husband walked out and filed for divorce,found out he was using steroids and has a girlfriend. he has threatened me during his tyrades and i now have a tempb restraining order. the hearing for the restraining order is in 2 days. he has our 7 yr old over night tonight with my 18 yr to supervise(tyhe steroid thing scares me)he is now using my sons cell phne to text me and tell me he still loves me and would i be willing to work things out. says if he stops seeing his girlfriend would i take him back...i love him with all my heart but am afraid he is just doing this so i will drop the restraining order. i want the courts to mandate drug testing and some counceling. i think he is bipolar...what should i do...do i believe him ????
