There is not enough substance there to make a committed relationship work.
After 3 months, dopamine levels from the early stages of a relationship start to wear off.
Then you start having negative judgments about the other person.

It’s better to figure this out in the early stages of a relationship.
Compared to going into a long-term relationship that leads to a worse heartbreak.
