You never gave it the time and attention that is required to maintain a healthy relationship. You planned things without including your partner.
Seemed to be shocked when he reached out to you while acting as if you expected him to ghost you, and generally didn't give off the impression.
It's OK to put on a cool exterior, but not if it causes you to alienate a possible romantic interest.
You put a prospective spouse through a rigorous battery of examinations to ensure they're trustworthy.
The issue is that you take so long to verify that someone is acceptable before continuing to seek a romantic connection with them.
They lose interest and give up attempting to win your approval. There are times when you just have to take a chance and see what happens.
You both avoided "buyer's remorse" by not making any final commitments to one other.
What if you were already in a relationship when you found the one? When emotions are involved, you feel uncomfortable.
If a connection doesn't develop into something significant, there's no harm in keeping your distance.
He was up forward and informed you that he wasn't looking for a serious commitment, but you still thought things might change when he got to know you.
He said it like it was, and you weren't being truthful to yourself. If you're looking for a relationship win, you can't choose someone.
If someone says they are not interested in a relationship, you should take them at their word and move on.
