Okay so here's the deal. Me and my boyfriend have been together a year and a half..

Bambi • A sound soul dwells within a sound mind, and a sound body.
.. And don't judge us for that, we are very much in love. He has two beautiful children that I love dearly. One of age 10, a girl, and one of age 5, a boy. He also has a crazy ex wife. One of the hypocritical, judgemental, Christian decent. She claims to be better than everyone and talks down to everyone. She talks complete shit about me and my boyfriend (mostly me) all around town and say very very vulgar things about me to the children. Now I got her reasons at first, until I realized who she really was. She isn't upset that she lost her husband, she's been cheating on him since the honeymoon. She ONLY argues in person and tries to fight and act crazy if the kids are present to watch. I used to be bisexual. She's called the police on me because I'm a "faggot" and shouldn't be allowed to live. That's what she told the cop anyways. She told the children I was a heroin addict. That's only a jist of who she is.
So anyways my point is she's crossed her limits with us. The house me and my boyfriend are living in, she had moved out a long time ago. She never payed anything towards it and has no rights over it.
My boyfriend wanted me to just move in here but, out of respect for his ex and out of respect for myself I won't live in the house they lived in together. So we are renovating it getting it ready to sell. My boyfriends ex breaks into our house. She tears everything up she came over here and had a party last week and had sex in our bed without permission, she left condom wrappers on the patio and beer cans and vodka bottles everywhere. She ran over our mailbox. She thinks she can do whatever she wants she thinks because it's her ex and her kid she has permission to come and go as she pleases. We've changed the locks we've talked to the police but we don't want to take a warrant out on her because it will make things difficult on her son and us. What's your advice to make our lives easier in dealing with this crazy woman??
