If I were my husband's sister. For her safety and her feelings she should just not talk to me and stay in her room or away from me and my child. Even if she's trying to be nice she should just save her breath and not say anything at all. Because she's disrespected me as a mother everything she says or does is going to piss me off. My respect for her as an individual is no longer there and I no longer feel like she deserves to be treated nicely. I'm trying so hard not to do something I regret. She should just really leave me and my child alone and find a place fast.
