Evil sis in law

I've been wanting to write a post about my sis in law for a long time. It's such a long story & don't want to get upset by writing it. I also don't want to write a novel. I'll try to keep this as short as I can. I met Anthony in 03 & we got engaged in June of 05. I never liked his sis, but tried to tolerate her for him. We started planning our wedding in June 05. She met a guy in Oct of 05 & got engaged like 10 days later & started planning her wedding. We were getting married in May of 06 in Bermuda. We planned on having a party when we came back here & it would be our wedding party, so our friends that couldn't go to Bermuda could go. She wanted to have her wedding the same day as our party & for us to have the party together. I said no way. We had been planning it & it was our special day. We had a fight & I had an anxiety attack. Ever since that day I've hated her. My FIL finally convinced her to have her wedding a different day. Everyone was on our side. Her hubby told Anthony's Dad that he couldn't wait for him & my MIL to die, so they could get all of their $. Even after that I tried to be cordial to her for my hubby. So we had our wedding shower & she came. She ended up giving me lingerie that she had bought for his ex-fiance. There was a tag on it that said 2002. Anthony got her to admit that she bought it for his ex. She said she didn't want to keep going out & buying things if he wasn't going to get married or something to that effect. That he should have just married her. So I was even more po'd after that. She still came to our wedding party on 6-12 & we attended her wedding on 6-25. It was really hard for me to be cordial towards her after all of this. Other things happened. We were trying to sell our house in MA. His sis & him showed up @ our house drunk & they both had to use the bathroom. We had a showing going on of our house & our realtor was in the house with a couple viewing it. She ran in the house & used the bathroom. He decided to pee on the side of our house outside in some bushes. We were sitting in the yard. Anthony was trying to quietly yell @ him & to tell him to not do that & how we had a showing going on. He didn't care. Her hubby is a huge loser, con-artist, fake etc..So is his sis. They're perfect for each other. Fast forward to Dec of 07. We had just moved to NH. Their Grandmother died a week after we moved here, she had moved in with them the June before. She made his sis the executor of her personal finances & all. I think the only reason they took her in was because they knew they would have access to her $. They bought a couple of cars, motorcycles, trucks, vans etc... I mean like 3 motorcycles (they would buy 1 & bring it back & get a new 1), 2 cars & a bunch of other vehicles. So they were just spending her $. Their G'ma left her only son (my FIL) $, Anthony & his sis. She did give Anthony & his Dad their $ cds that she left them, but she somehow ended up with all of the $. She lied to our lawyer & said she gave her dad & Anthony their $. Anthony has a lawyer friend, but didn't want to spend the $ to have her get the $ from them. He did have her send a letter asking for them to list exactly where the $ went, but they never replied to it. So we haven't seen her or him for a year & 1/2. So on Saturday, the day of Tara's party I went down to get the mail. I opened my garage door & there was a car sitting there in our driveway. I didn't recognize the person & just thought it was 1 of our guest's hubbys that I hadn't met, there early. So I said hi & then it hit me who it was. So I said very rudely "What are YOU doing here". He said "she's dropping off presents" (for Tara). So I continued to walk down our hill to the mailbox. I came up the driveway & his sis was just getting in the car (A brand new car I might add). They had the windows open, so as I walked by I bent down & looked inside & said "Oh, you got a new car with our $? Real nice" (sarcasticly). I slammed the garage door & went inside. I went upstairs & Anthony was pretty shocked too. Opening the door to her. She didn't say much & gave him a huge horse stuffed animal (that she must have gotten @ a yard sale for 50 cents) for Tara & another wrapped pres. He didn't know that D was there too. I was litterally shaking & had another anxiety attack. After my anxiety attacks, my head usually starts pounding. So it did. I couldn't believe this happened the day of T's party. I think my MIL mentioned the party was that day & she didn't know that D would show up too. So I somehow have to let his parents know how she isn't welcome around me or my daughter (another fight). I was thinking last night that I would like to have a restraining order against both of them, so they can't come on our property & near Me or Tara. I haven't mentioned it to A yet & I'm pretty sure he's going to say that I can't do that. I also don't know the details on getting a restraining order. If you actually have to be threatened. It seems like the few people that I know that have them against people got them pretty easily. But I'm sure that A will be against me doing that. Him & his Dad aren't really mad @ her, just him. They think she was brainwashed by him. I think she's a money grubbing con-artist & knows exactly what she was doing. So it's really hard dealing with this. I had hoped that I would never see her again, but knew that someday she would come back into our life. I lived in fear of that. I won't be around her & go thru' anxiety attacks. I also don't want my daughter around her. So I really wanted to vent about this & get it all out. I keep waiting to see them on the news that they conned the wrong person & got arrested or something I'm sure he's done this before. I'm surprised that he's still around & hasn't left her & took off with all of the $ yet. I do believe in Karma, it just takes so long sometimes.
