I left my ex almost a year ago. He's fighting me in court to see our son but the courts have refused and said he's too dangerous. He abused us both and is a horrible, dangerous human being. I moved over 100 miles away from him but still talk to his mum who is really supportive. I was friends with his brother's girlfriend. I'm going to call her his sister in law just to make this post easier to read. He knows a few things about me that only a few people knew and I've become overly paranoid. His SIL wants to keep in touch. She refers to my son as her nephew and obviously misses him. She only knew him for 2 months after he was born though. I like her but would be fine if I never spoke to her again. It's harsh but true. At the end of the day she is with my abusive exes brother. It feels weird staying in touch with her and makes me nervous. Am I awful feeling like I don't trust her and that my gut is telling me to stop talking to her? I feel so guilty about it.
