Bubble

This word has been used for a couple I hang out with. A friend said, " They are in the Love "Bubble".
Meaning they are so in love that they are oblivious to what is going on around them. They are in the "bubble". The " Love Bubble".

A relationship between two people that cannot be penetrated or interrupted. Two people who are in love and don't notice anything going on outside of their Bubble. To be in the bubble you are oblivious of your surroundings. A relationship that is so hot you only see each other. You are in the Bubble!

That couple is in the bubble.
Remember when we were in the bubble? Now we are a old married couple.
