I'm going to ghost/block my wife's number during a work trip
Why do you want to block her number?
Because she has been calling me off and on lately and I can't handle a long phone call.
It can be annoying to get calls all the time especially during a business trip but you shouldn't just block her. It will lead to a fight, it is better to talk to her about the problem.
Haha, good one. Why don't you join us in helping our problem out?
I'd love to help you guys out, but marital problems should be dealt more in private. How would your wife feel if you told other people about her problems, on top of ignoring her? How about asking her why she wants to call a lot instead of just blowing her off?
