I've never posted to this forum before, but when I saw the topic it really hit home for a good friend of mine. My roommate's ex bought a dog with her with the understanding that they would care for the puppy together. A few months ago, he left her and even though she wanted to keep the dog anyway her ex didn't offer to pay for half of her care like food, vet bills, spaying, and other stuff that comes up when you have a pet. Maybe I shouldn't assume this, but you sound like you have done the exact same thing and are justifying it with the reason that your ex wanted the dog and that she "doesn't want anything to do with me." You didn't say anything about paying your part for your dog's care and sending a toy is hardly doing your part, so that is why I recommend that you not get another dog. You seem very fickle about this, and I won't comment about why your ex "doesn't want anything to do with me" but based on what I have read here I can kind of see why.
