You are drawing wrong lessons learned. So it seems. It seems that your lesson learned is not to have nude pictures taken. You need to look at how not to get involved with people who are manipulative, unstable, abusive, threatening, intimidating, controlling, dishonest, etc. This is because if you draw out of it "do not pose nude" as your lesson learned, but not the part about "manipulative, unstable" etc., then something else bad would happen - not this but something else.

So you need to look more broadly.

Not by way of reminding you but by way of catalyzing learning so that you can get a broader, proactive, forward looking solution to the general issue. If you treat this as a learning experience, you won't feel so foolish, after all.
