Those who are intrusive aren’t always trying to get attention. They may interfere in others’ affairs by accident. Let’s say Jon goes into the living room to relax, only to find Lily and Jane having a private conservation in there. In this case he’s being intrusive because he’s unintentionally invading something he isn’t meant to be a part of.

Being obtrusive means being much bolder with the interference. So let’s say Jon knows knows that Lily and Jane are talking in the other room and barges in wanting to know what is going on. In this case he’s obtrusive because he’s intentionally invading something he’s not meant to be a part of.

Perspective is another difference between the two words. Intrusive is often from the perspective of the one being intruded upon.
