I do agree with puppy that both you and your W do not seem clear on what the situation is.
It sounds a bit as though your W has a problem with responsibility, and of course by running to OM she absolves herself of the family responsibility and leaves it to you. If she were actually to be with OM she would soon find that he wasn't any sort of answer....in fact by saying she is going to move away from both of you she seems to be actually recognising that.
It sounds to me like your W doesn't really know what it is that she wants / what is bothering her. Therefore you have to just look after yourself and your resposibilities. Prove that you are reliable.
