I'm done. Not controversial but advice?

Kirsten • Im Kirsten, & I'm a mommy to Jazmyne

So, my fiancé and I have our own place, a 4 month old baby and a 1 year old dog. We're going to be getting another dog and his mother pisses me off.

K, she called him yesterday and he told her were getting another dog and it's going to be my companion because I have anxiety, depression and I have high functioning autism but I can't go to a store without having anxiety of all the people. Anyhow, she says with a snooty attitude "how do you expect to feed and care for THAT dog?" Fucking really. Okay, so I go and make a post on my Facebook because I'm very hurt by her. She bashes me all the time. Today, she called him ABOUT MY POST. Started talking shit about how the puppy newness is going to wear off and you're just going to be left with this dog that you're not going to care for. Really, bitch? Really. What I buy with my money and how I care for what I'm buying shouldn't concern you. She's neglecting the fact that it's a companion animal. Done. 👌

Advice? Please before I freak the fuck out on her.
