I moved in February and decided to cut down my collections a bit too. I got rid of more dolls than ponies, but I let go of many G3s because I realized I didn't even like them that much. Some of them I tried to sell but for the most part I just donated them.
A month later I left my abusive husband and I had to be very selective about what I took with me because there just wasn't enough space. I took most of my ponies and dolls, but a lot got left behind. It really forced me to decide what was most important to me, what I needed, what I could replace, and what I just didn't want at all anymore. I had a few regrets but I was able to get everything back.
