So i have a friend that recently split from her long time partner. They are going to mediation to work out the custody of the kids. She has asked me to write out a letter on my opinion and I dont know what to say because I honestly think right now she shouldnt have full custody.

So firstly their relationship was horrid but she said just as much crap to him and he did to her. I physically never witnessed it because we are now 6hrs apart but on the phone or xbox chat they would yell and scream at each other. She says he apparently doesnt help with the kids etc when he is home (he works 1 week away and then 1 week home) She has said thinga but i havent witnessed it myself. All Ive witnessed is their yelling and screaming so loud it is deafening (even yelling at the kids)

Secondly mentally this friend is a mess. Shes all over the place. One morning she will be saying she has tried to kill herself. Next she is perfect. When they initially split she told me she tried 8 ways to kill herself. She also went missing and I was bombarded by people asking if i knew where ahe went (i live 6 hrs away!!) So I called the police and voiced my concerns. I do think she only says it for attention but the one day I dont take her seriously will be the day she does do something.

My issue is until she gets herself together mentally, I honestly think she shouldnt have full custody of the kids. Dont get me wrong, she should be allowed to have them over a weekend or something. But until she has another house. Has a stable mental state where she isnt trying to kill herself so much. Etc i dont think she should have the kids 24/7.

But she is asking me to write a letter with my opinion...thinking Id bad mouth her now ex. She also wants him back (despite him cheating twice and already seeing another girl... not even 48hrs after they split) and if I do write bad stuff...she gets back with him like she has before. Im now the bad guy.

I just dont think I want to get involved at all. She wants me to lie and say nasty stuff about her ex. When all I care about is the two kids....but she expects me to. I dont know what to do anymore.

Any advice?
