Jen, you have to do what is best for you. If you want rats again (and the suckers are hard to resist!) then go for it. Most of us know that snakes take time & money and if you are in short supply of that and need to step away from your dreams for awhile until you are in a different place, then do it. I won't think any differently of you, nor do I think other people will.
I love my snakes but you are right when you say that they don't give you the affection that a furry pet will.
