2. Dakimakura will never voice any unhappiness. You could be doing something that makes your hug pillow miserable but it will NEVER tell you so. Do you really want a relationship based on one member's unwillingness to disagree with you? Counseling will also never help. You'll do all the talking.
3. You cannot protect yourself from the greed of a dakimakura waifu. By this I mean, your hug pillow can't sign a prenuptial agreement. It has no hands.
5. You cannot divorce a dakimakura easily. Similar to the above, your hug pillow can't sign divorce papers, which means you'd have to go through the much longer and more painful process of a contested divorce, in court.
I hope this appropriately cautions you from making an honest pillow out of your dakimakura. I applaud your devotion, but you need to do what's right...foryou.
