A lot of English learners mix up adjectives ending in ED and ING. The meaning can be quite different.
I’m bored. (= I am not interested / entertained.)
I’m boring. (= other people are not interested or entertained when they listen to me.)

——————————————————————————————–

Adjectives ending in -ed show what has happened to a person or thing.
Adjectives ending in -ing show the effect which something has on a person or thing.

Example: If you meet someone who makes you laugh then he is amusing. You are always amused when you speak to him.

• My girlfriend is bored. – (My girlfriend feels bored)
• My girlfriend is boring. – (My girlfriend is a boring person)

• I am confused. – (I don’t understand something)
• I am confusing. – (I will cause you to be confused)
