You never gave it the attention and consideration that are necessary in a 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 that you cared about maintaining a steady connection.
The issue is that you take so long to verify that someone is acceptable before continuing to seek a romantic connection with them that they lose interest and give up attempting to win your approval.
You put a prospective spouse through a rigorous battery of examinations to ensure they're trustworthy.Sometimes you just have to take a chance and see where the wind takes you.
You weren't interested in getting married if someone better came along. If you were in a relationship and then found the one, what would happen? When emotions are involved, you feel uncomfortable.
It's safer to maintain your distance, and if the connection doesn't develop into something significant, there's no loss.
He was forthright in letting you know that he wasn't keen on a romantic attachment, but you were sure that as he got to know you more, he'd alter his mind. But he didn't do that.
He was forthright, but you weren't being honest with yourself. Relationship games can't be won by picking someone only because they provide a difficult obstacle.
You made the courageous and healthy choice to quit the relationship because you are too busy to spend time on almosts and not good enough.
People are naturally attracted to you because of your self-assurance, so you won't be lonely for long.
