If I don’t care too much about you, then only green will be left. What does this sentence mean by a man?

"If I don't care about you too much, then only green will be left" means: If I don't care about you, and I don't care about you, you will cuckold me.

This sentence reminds me of my best friend’s boyfriend:

My best friend is a very fashionable person who likes to dress up and has a beautiful figure. Judging from her appearance and body shape, it is easy to attract the opposite sex. Despite the provocation, my best friend was not moved, and in the end, she chose to date a colleague in the class.

My boyfriend was very generous at first, and he also understood in his heart that it is normal for beautiful people to be missed by others, as long as his girlfriend loves him. But as time passed, the lack of sense of security became serious, leading to frequent quarrels between the two.

Later, two people had a quarrel, and my boyfriend said this: "If I don't care too much about you, then only green will be left." It means: Just because I care about you, I am entangled, That's why you care appropriately. Otherwise, my head would be full of cuckolds.

Yes, when you are in love, you must give the other person a sense of security. If there is no sense of security, it will be difficult to continue this relationship. Even if he loves you and cares about you, he will slowly choose to let you go because he is really tired.
