I read some book where with "maturity" AVPd can become something else. When I read the diagnostic criterion they seem to describe me but maybe more so when I was younger and if it's all about self esteem that's also said to be the root of other disorders, if not all of them. If AVPD is about that, then narcissism is also said to be and from anecdotal evidence I've heard that they have difficulties with intimacy.
Avoidants are said to hate attention though and narcissists thrive on it. There could be a need in avoidants to distance themselves from others. Perhaps it's motivated by the same desire to dismiss anyone that doesn't like you in both cases.
Maybe another example would be to engage in intimate relationships and feel dependent on them even though they're disfunctional. You're not entirely comfortable with the person and they can make you feel anxious or trapped. You're trying to make the relationship work though out of fear of rejection but probably just end up not knowing how to keep them happy and letting them run everything, including how you have to wait for them to call you when it's convenient for them, whether or not you actually feel like chatting at the time.
