Homecoming following an Underway

Hello, it’s my fiancé’s first underway and homecoming is coming eventually. For those that have been the sailor, how are things when you come home? Is there significant changes/adjustments coming back from submarine?

For the spouses, is there anything I should expect? Should I wait to present ideas of travel and things I want to do with him? I don’t want to overwhelm him

Typically he is a very even keen and stable person so I’m not worried about like PTSD/mental issues, however I don’t know what a submarine does to a person!

I just want to be the best spouse to him following this time. I know he’s told what to do for 100+ days so I just want to make his transition home as restful and enjoyable as possible. Thanks!
