So I think you are asking how dopamine causes you to "feel" something...
It doesn't. Dopamine causes you "want" something. As I understand it is a chemical code that causes you to want closeness to something. Like if you were to program a mobile robot every time it saw a particular image to move closer to it. The robot does know why it makes the choice to move towards this object every time however it retains the memory of always doing so.
These chemicals are the programing language of the brain. Like the chemical vasopressin instructs you to display protective behavior. If it were missing, parents would not receive the instruction to protect their children.
So perhaps we don't actually "feel" love. We are just following a chemical code which causes a certain behavior which we call this behavior love.
The feeling part is an illusion. Not that you don't experience the illusion of feeling love, only that it is not what your perception of it is.
Love is a set of chemical instructions(code) which causes you to behave in a certain way. We only perceive it as something that it isn't.
Illusion like a mirage. If you see a mirage you cannot not see it. It is real to your perception. However it is not as you perceive it to be. In the case of a mirage, we know the physics which causes us to "see" what is not there.
So love is a mirage. At some point, just like a mirage, we will understand the physical process of why we seem to be feeling these emotions as we go about life. IOW we don't "feel" anything. We just perceive these chemical instruction being process by the brain as feelings.
This is how I view it from everything I've learned about it so far. If new information comes along I might have to change that view.
