'submerged' in this particular moment [closed]

How can I say this sentence more properly? Suppose I am with my girlfriend, and I say

"I want my whole life to be submerged in this particular moment".

I don't think that submerged is the right word. What I want to say is that I want my whole life to be in this particular moment that I am with my girlfriend. Can any one construct this sentence so that it sounds pleasant and correct?

Immersed is a possibility; immerse has sense “To involve deeply [eg] The sculptor immersed himself in anatomic studies”. “I want my whole life to be immersed in this moment.”

Also, quintessence (“A thing that is the most perfect example of its type; the most perfect embodiment of something; ... The essence in a thing that is its purest and most concentrated form”) may be relevant, as in “I want this moment to be the quintessence of my life”. Either of these examples (with immersed or quintessence) sound well enough, but whether they are sensible things to say is another issue. For one thing, it isn't clear what it means for a life to be immersed, or submerged, or quintessentially found, in a moment. For another, the subtext to “I want X to be Y” is “but it isn’t Y”. Perhaps drop the “I want” part.

The word you're looking for is subsumed.
