I sanded and painted a dresser with several coats of 100% acrylic paint, namely, these paints:
The paint job turned out good, with one issue. After 4-6 weeks of drying, the paint is still slightly tacky. That is a problem, because when I put a significantly weighted object on top of the dresser and leave it on for a while, it 'peels' off. If I leave it for long enough, I am sure the paint will completely peel off along with the object.
The reason for the tackiness could be for a variety of reasons (I probably didn't allow enough time to dry between coats, and I probably put the coats on too thick) but I am more concerned about how to fix it so that the top of the dresser is not sticky anymore. Short of restripping it and starting over, what are my options?

It's called "blocking" and often happens w/latex paints - especially if the 1st coat wasn't allowed to dry fully before the second coat was applied. It's not much of an issue on walls, but horizontal surfaces are a different story.
The ultimate solution is time - possibly a few months. The inner coat's moisture is blocked from evaporating by to outer coat. It will slowly wick through the surface over several weeks.
You might be able to reduce the stickiness by spreading some fine talcum powder on the surface, then lightly vacuuming it off - but TEST in an unobtrusive area, first, because if it's too sticky, you could end up with permanent, visible, dust built into your paint job.
You may be able to speed the process by blowing warm (not hot) air across the surface for several days (hot air can cause the paint to peel). This can open the pores in the paint to allow slightly more rapid evaporation, but a lot depends on what paint you used, how much moisture is trapped in the undercoat, etc.
