My sister in law hates me for no reason.

I just need to get this off my chest and get advice. Because I am 7 months pregnant and have a 4 year old and don’t want to get physical.

So me and my husband had an argument and stayed at my mothers for a day.

The next thing u know I get a message on SnapChat from my sister in law saying how immature I am and that I need to grow up. Mind you she’s 18. And no it’s not my husbands sister it’s his brothers wife...

she also told me that I’m disrespectful because I don’t hug my mother and father in law but yet nobody does but her. And I get along fine with them.

She also said that because my husband pays all the bills I have no say so in his life. That he could do what he wants. Because she’s in the military and has a house on base so she thinks she’s better than me mind you she’s only been with my husbands brother for a year and she’s been begging him to have a baby with her and he says no cause he doesn’t want to work.

I told her me and my husband agreed that I don’t have to work. She said “don’t play that pregnant card with me” that I could get my ass to work. Like if she’s my mother 😂.

She would always make ugly faces to me in front of everyone ever since I got pregnant.

Not only that I have to see her Saturday for my baby shower but then there flying out to Arkansas for 2 years.

I am not looking forward to the baby shower at all 😞 I know it’s my day I’m the star of the party but honestly I just wanna be in my room the whole time. I don’t want to invite her but that’s my brother in laws wife. I honestly don’t know why she hates me so much I’ve never did anything to her.

What should I do about her Saturday?
