If they split up, then you (probably your son) can kick her out on her own.
if they get divorced, same thing.
since they are married, if you try and kick one out, then they all will probably leave.
it would be hard to evict just her, instead of the whole family.
or you could let this ride, and then see if you son does break up with her. then she could leave, and wouldn't be stable enough to have a chance to fight for custody.
