Treating me like trash

My S/O is treating me like crap because I don’t want to have another baby. I am day 22 on my period, something is wrong with my body I don’t want to risk anything and the big thing is we fight way too much. Im told to pack my stuff and leave almost every argument, I have 2 kids I don’t need a third involved in it. She’s a bully... I’m not doing it. I was asked “them why are we even married if you don’t want another baby”. Uh... because marriage doesn’t revolve around having babies... it’s about 2 people who love each other. It’s my body, I say no.
