If I remember correctly, on your last thread you weren't prepared to help your wife with travel costs because you felt she hadn't saved for retirement as well as you think she should have.
If that is so and this is still going on, maybe you need to decide if you are willing to change and support her so she can stop having to work. Maybe then she'd be able and willing to accompany you? If not, then she is tied to keeping working which will stop her from having as much ability to travel. If these obstacles are removed and she still doesn't want to travel and it's not resolvable, you'll have to consider other options like travel alone or with another companion. This can only be worked out after a good heart to heart with your wife.
I can't understand in any way why you wouldn't help your wife with travel costs surely you are a partnership in every way including money matters.When my late darling man was working and I was working all our salaries went into the same pot and used for holidays/breaks as and when we wanted either together or separately with other friends.
