Relationship problem!

I feel and I admit that I am too childish and immature in relationship stuff. Life have not trained me well in relationship stuff. That is why I prefer to be single now.

I think that I had hurt her due to my crazy, stupid and immature act. I feel bad and I feel that I am doing the wrong thing. I should not rush and panic in relationship stuff. I should slow down my pace and get to know each other well first.
