If a relationship stops you from doing the things you want in life it's not a good relationship for you. You might love them extremely and they may back but they are holding you back from a satisfied end and that isn't something anyone should let happen to themselves. (Parental obligation aside of course)
We actually don't know the whole story. What if she was pregnant? What if she was sick? What if there was some other thing which was of far more importance than the trip?
Guranteed, there are people who are like the ones mentioned above but, not everyone is like that.
It doesn't say couldn't go. It said wouldn't let go implying controlling behavior rather than obligation. It also implies that given the choice himself he would have gone.
It would say wouldn’t go even if it was couldn’t go though. This was only posted to get likes and a wife not allowing someone go somewhere is funnier than some sick family member or any other reason making him unable to go
