Do any other ENTPs get some strange pleasure out of artistically sabotaging relationships? Or is that just a general dysfunction thing?
Well, I have noticed when I begin a relationship that I tend to "test" people. I think it's because I am so guarded and cautious that I want to make sure someone really cares about me. This might seem like sabotage.
"Create like a god, command like a king, work like a slave."
"How dreadful!" cried Lord Henry. "I can stand brute force, but brute reason is quite unbearable. There is something unfair about its use. It is hitting below the intellect." ~ Oscar Wilde - The picture of Dorian Gray
the only person an ENTP likes to sabotage is themselves. According to my friend (an ENTP), he never goes out with girls unless they're bitchy. And by bitchy I mean the type of manipulative person who talks crap about the other person all day long (even their partners!)
Apart from that, I don't think ENTPs in particular like sabotaging others. It's more of an upbringing kind of thing.
Self-sabotage. I know a thing or two about it. My friends always comment on my choice of romantic partners, and the lack of cohesion or pattern in my choices. They say that I piss in the gene pool quite frequently. In a way, they are correct because I never set out looking for the perfect mate, in my mind he doesn't exist. I don't even actively look for partners, it never crosses my mind to do so. I've always felt I was destined to single, and I've always been completely fine with that. Life is good either way.
I fill up my days hanging around people who *interest* me. But the problem is that pretty much everyone on the planet is interesting to me in some way. I chat with everyone from the cop to the robber, equally fascinated by both. So, as I explore humankind, I tend to fall into relationships with those who simply declare themselves to be my boyfriend. I guess after a certain amount of time has passed, and I'm still hanging around, they feel that this is the next logical step or something. It's the only thing I'm pretty passive about in life. In another thread, I've equated it with being clubbed over the head and dragged back to the cave. I usually get stunned at first, then the lack of oxygen makes me drift into sleepy acceptance for a while. After a few months I slowly process what just happened, panic, then I furiously gnaw at my own foot in order to escape the trap.
It doesn't matter if said person is in fact the perfect choice for me, the point is I feel trapped since I never made the active decision to be in that relationship. And then the need to escape becomes overwhelming, if only on principle alone.
