He may have rejected you because he wasn’t feeling a true connection with you.
Even if the both of you began your interaction in a promising way, that doesn’t mean that it will always stay that way.
Perhaps he felt that there seemed to be a connection between the both of you at the start of your interaction.
However, as time went on, he may have realized that there wasn’t a true connection.
It may have been something that you said in a conversation that you have had with him that made him come to this conclusion.
It may have been a way that you go about thinking or drawing conclusions.
It may have been a sense of disconnect as time went on as he realized that the both of you may not have as much in common as he had initially thought.
There could be a number of reasons why he rejected you, even when everything seemed to be so promising at the start.
Do understand that, oftentimes, people just get an initial sense of someone and how they are.
That initial sense is often what will spark interest.
However, as they get to know and interact with the person, that initial spark may start waning.
It can only last so long.
Oftentimes, that initial spark is supposed to be replaced with much stronger interest as they get to know the person better.
If much stronger interest doesn’t develop while that initial spark of interest is still present, that spark will ultimately fizzle out and the interaction will have no chance of progressing to romance.
This may have been what happened with this guy and why he ultimately rejected you.
You should also consider the possibility that he may have rejected you because he isn’t ready to get into a serious relationship with anyone at this time.
He may have bigger priorities in his life.
Hence, he may just not feel that he has the time or emotional availability to expend on someone romantically.
This is obtain evidenced by how many other girls he may be talking to simultaneously.
If you have come to notice or become aware of him constantly flirting or talking to other girls, this may be your proof.
He may simply enjoy the attention that he gets from girls but once his interaction with them gets to a certain point, he may pull back and stop it altogether.
He gets to a point where he realizes that the girl is getting serious.
They are no longer just having playful banter or lighthearted flirting.
Now, she is constantly asking him about his feelings or whether he is talking to any other girls in the same way that he is talking to her.
The fun interaction has now given way to more serious questions being asked and he gets worried.
He knows that if he were to continue this interaction, these serious questions will become more and more constant.
She just isn’t as much fun as she used to be and things will only get more intense.
As a result, he chooses to stop interacting with her and move on.
He was never looking for a serious relationship in the first place.
