You don't 'get' him, he doesn't 'get' you.
I know you feel like it sounds really silly to say you want to listen to Pearl Jam on high volume with someone who knows who they are, but it's not daft. That's exactly what I want (not necessarily with Pearl Jam).
I don't care if someone hasn't heard of Tom Waits before me, as long as they completely fall in love with him when they do 
But it's not wrong to want to have fun. And to want to find the same things fun.
I'm 39 and I still wear dresses with DMs. I want a man in his 40s who still wants a woman l who wears dresses and DMs.
I want someone who is as happy bake bread with me as they are to laugh and get grossed out watching Braindead.
I want someone who will get up and make me brandy and warm milk in the middle of the night when I'm not feeling well and someone and who will make crazy outrageous plans for starting a band...
And yes, I want him to have similar attitudes to me when it comes to finances and parenting, etc. But, to be honest, at the moment what I really want is someone who makes me feel 17 again when I'm with him.
And why shouldn't I have this?
In fact, I have sort of found this.
And he wants all those things too.
I'm increasingly of the opinion that life is too short, and if it ain't working, change it. Decide what you want your life to look like and make it happen.
