More than likely he has been hurt before and he hasn’t had a chance to get over it.
He may very well like you and want to be with you, but he’s not quite sure how to show that emotion.
If the other person is intimidated or scared and runs away, better early on then months or years down the road.
I don’t want to be in anyone’s life that doesn’t want me in it.
I truly believe being able to express emotions is a sign of strength, not weakness.
You don’t want to try too hard, but rather you want to allow nature to take its course.
This hands-off approach may actually work well to your advantage.
