Ruminess 

The heightened state of happiness.

Used to expand upon happiness with more emotion and feeling

Being in a relationship with you has made my life full of ruminess.

ruminesce 

To ruminate and/or reminesce (longingly and perhaps with no small sense of loss) as to something or someone no longer available or present as it once was.

to ruminesce; perhaps exemplified in the emotional ode to Chrissy Hynde's vanished home:

"I went back to Ohio
But my pretty countryside
Had been paved down the middle
By a government that had no pride
The farms of Ohio
had been replaced by shopping malls
And Muzak filled the air
From Seneca to Cuyahoga Falls
Said Ay! Oh! Where did you go, Ohio?"

Marinating in the past.

Emelia was ruminescing about how she didn't eat the fourth taco. Now she was sentenced to starvation.
