Hi and welcome,
Had the topic of children ever been discussed prior to this?
Does your wife have any diagnosed personality disorders?
Springing a week long visit on somebody is one thing ....but being kicked out of your own bed is another. How does one do that successfully? ... Just in case I might want to try that some day. Then come up pregnant after said visit ...wow. I can see why you have lots of conflicting feelings.
Have you considered talking with a counselor?
