Every time I see this thread I think of a song that’s actually pretty much the exact polar opposite of what the OP asked for. The entire song is saying “Break up with your hippie boyfriend and date me instead.” But I’m posting it anyway. 
I don’t have a song at the moment, but I did marry one. Happy for 40 years. I still miss her. 
This one has nothing to do with marriage, but does concern a hippie gal. Probably NSFW.

“I want to rock your gypsy soul, just like in the days of old”
Slightly non sequitur, but I always think of this song as “Nothing Grows Where My (fill in name of dog) Goes”.
Not just you.
But I always thought Rosemary herself “goes” all over the grass. And she isn’t a dog.
I always wanted to eat oranges with Suzanne. Here is an interview with Suzanne.
