Yeah pretty much with this person said.TheNumber1Zero said:Upon revealing their feelings and hearng "No," they feel embarrased around you.
Only natural.
For further explanation, put yourself in this situation.
Imagine there is someone you like, I mean really like. You ask them out and they shoot you down.
Now imagine having to be around that person on a regular basis for what may be a majority of your life.
Understand?
After you go as far as asking someone out, if they decline, there's always going to be that awkwardness in the air. You might not intend it, and honestly have good intentions, but they will always remember that you shot them down.
