Need to vent

My sister in law has been pissing me off more than usual lately 
Ever since I started dating her brother she has called me a gold digger and said that I'm gonna leave him when something else comes along and that I'm lazy because I haven't found a job yet, even though I have applied at a bunch of places , it's not like I'm gonna get the first job I apply to , and she says that I keep my husband from her kids and I was hoping it would change once he and I got married but it is still going on , and my Facebook removed her from my friends list and I didn't know that it did that till my husband showed me the 12 MESSAGES she sent him while he's working "thanking" me for removing her from my friends list and removing all the tags of her and her kids/family from our wedding pics but yet when I checked the tags are still there , and she said that she doesn't want me anywhere near her, her house or her kids anymore , and that she's glad he married such a bitch . Even though I have been nothing but nice to her and my husbands brother in law and kids love me , and even her husband hates that she treats me like this , and she flipped how she is 
She told my husband that she's been nothing but nice to me and I treat her like this but yet it's the other way around and she's even told my husband I keep him from seeing his niece and nephew which is bull, I would never do that to him and I love those kids, and she says we never go to any of their activities (swim team, soccer , softball) but she knows that my previous job scheduled me a lot of hours so it's not that we didn't want to go , we weren't able to get away from work. And I just found out she posted some stuff about me on Facebook .
