I'm not going to be friends with someone anymore
Why don't you want to be friends?
He never calls me. I think we had a good time together, but he doesn't call me anymore.
It is understandable to end a friendship if it is not working anymore. If you are the one making all the contact, it can be frustrating and could lead to anger and worse feelings.
That is true. What I should do more to keep the bond?
Sometimes there's nothing you can do. Some people are just not interested in being friends with someone even for odd reasons. Don't beat yourself up about it and find a new friend.
