Trigger warning ⚠️

I’ll try to make this short. My ex husband was a very bad man. He abused me physically and sexually in which I conceived from that abuse. It got so bad I finally got brave enough to press charges and he has been in jail ever since. My daughter is almost 3 and I have found new love and am engaged. My daughter never had a bond with her bio dad and was truly frightened of him because he was angry all the Time (he never hurt her in any physical way) anyways my daughter calls my fiancé dad. He is amazing with her and has grown so close to her. He now refers to her as his own daughter. He helps do everything her dad should’ve done therefore I love that she calls him dad. This pisses my ex mil off. I used to be extremely close to her and she is a master manipulator so I always let her talk me into giving her son a second chance.. which I regret fully and feel so dumb about. You’re probably thinking “why is this lady still in your life” she is a Parasite. No matter what I do she creeps back in and uses the “I’m her grandma” excuse. I don’t feel safe with her around my daughter and truly want her out of my life. She calls my fiancé bad names and even tells me she’s going to come her and get my daughter herself.. I’m ready to take legal action against her but she’s psychotic so I’m terrified. Please tell me I’m not crazy
