Personally, I've gotten the "unavailable" accusation quite a bit--something I've actually been trying to work on as of late.
The downside of all this nonreactive power grabbing DJ stuff is that it's really easy to come off as uncaring in the context of a relationship. You need to strike a very delicate balance--you want her to realize that you have options and aren't afraid to walk if she does not treat you like a king, but you don't want her to feel insecure in the relationship. Those feelings of insecurity come when you're TOO MUCH of a challenge i.e. acting indifferent and disinterested, not treating her with love, etc. While under the right conditions this can raise her interest level for a while as she clamors for your affection, too much consistent, unrewarded challenge has a negative effect on a relationship. A woman, after repeatedly seeing her good deeds gone unrewarded, may start to view you with frustration and resentment, or, worse, withdraw to protect herself and start looking for other branches.
At first when you study DJ philosophy, it's easy to fall into the trap of believing a DJ is purely an anti-AFC--the "bad boy" archetype. In a way, this is correct--but what people fail to see is that it is not the ACTIONS that define an AFC, it's the INTENTIONS. It's GOOD to pay special attention to your girl and take her to do fun things and tell her you love her--but only if she's earned it. Otherwise, it's NOT GOOD.
I think the key to maintaining a healthy relationship is to demonstrate love from a position of power, and not just to work at holding that position of power at all costs. If you hide your feelings and don't even show a TRACE of jealously (or any other AFC emotion) when prompted, you will eventually have to answer to accusations that you are not human...
...Of course, if you're not interested in relationships, it's MUCH better to be unavailable, as it causes less harm to the girls when you break up with them.
