Partner with GAD, always feels the need to be excited

Hi everyone
I’m the long term partner of a man who suffers GAD. He’s had it 10 years now (diagnosed).

I’ve realized one thing about him, he can’t stand it when life isn’t ‘exciting’.
Most of us go through their day by following a certain routine and so does he.. the problem is that he’s pretty bored of this.. his work bores him, his friends bore him, I bore him.

As a person he has always had this NEED for excitement, something new, something thrilling.. and when that lacks he gets extremely anxious/ frustrated.

This question and the background of his ‘issue’ is hard to explain, but does this relate to anxiety or GAD.
Does anyone else with anxiety/ GAD always feel like they NEED to be excited about something?
And if so.. why is this?

Thank you everyone
