He's back home, long story.  Hopefully they can work things out.  Thanks for your suggestions!

I don't know how things work where you are, but I'm sure there are support groups that can help her!  The best thing you can do is be a friend to her and not take sides. 

In some countries, she will eligible for financial assistance.  I just hope that she gets straight in her head what she wants.

I'm the kind of person that would not tolerate that from my partner, and would tell him he can move out permenantly.  He wants to play games, then he's not doing it around my kids! lol.

So sorry to hear about your friend. Hopefully if he just walked off he doesn't really have any plans of leaving her high and dry, but just an impulse of anger. If he has gone off but come back before and since it is his parent's house and not his own place or anything semi-permanent like that, it probably means he's not planning to just ditch them all. Of course one can't really tell for sure, esp not knowing the people involved, but I think to help, just be there for her. The situation is really between the two of them, so you probably can't do much there, but you can help her get through the low points by just doing what you are probably doing already, spending time with her and listening to her even when everyone else is tired of it. I'm sure it must be frustrating for you as well to feel somewhat helpless when you want to fix it.

i feel, that you should just offer any support you can give, you will help her anyway you are able,(being supportive etc) i would hope the husband isnt just leaving and leaving her to fend for herself, and while we hope its not permanant, she needs to start planning, in case, find financial support,hard, but it has to be done now better to be planning and not need to use  the help then to wait annd fall short, good luck hun, its hard seeing your friend split and not know what to do, keep us updated please hun xxx
