Simpson dear, it doesn't have to be a waiting game at all. Do you think you can just sititout and it'll magically get better? Him showing you a return ticket means nothing until that plane is off the runway with him.
Sorry to put it so bluntly but the sooner you seek advice the sooner you'll find a way to get that house transferred into your sole name. Your little ones must notice that you are anxious, for the sake of them and some breathing space for yourself, go to a solicitor or seek counsel with a charity to find a way forward. Sitting it out will just leave all of you hanging in suspense.
