I think you really need to find out the reasoning behind him saying no. Does he hate animals? Is it because he doesn’t want the responsibility of owning a pet? Is he just being difficult, and doesn’t realize how much you really want this?
If it’s because he absolutely hates animals and there is no hope of him falling in love with it, it would be a bad idea to bring one into the home where it may be mistreated. Especially a Yorkie, because as mentioned by another poster, they are difficult to potty train and can be very frustrating for someone who didn’t want it to begin with.
My fiancé said no when I first asked about getting one, but I could tell he didn’t mean it. I just kept mentioning it and it only took a couple weeks until he sent me a text with a pic of a puppy that said “okay!” Now he is more in love with Jaxon than I am (if that’s even possible)
I guess you need to be able to read your spouse and if it’s something that he is truly dead set against, there may not be much you can do. Aside from picking out the puppy and dumping the hubby!!
