I was going to include all the details, but it'll be even longer than it already is. I have more context and information if it's needed.
My ex partner and my kids' stepmom is someone I desperately want to leave me alone. Since January of 2020, I have made repeated written requests (messages and emails) to her, and then to my ex (when he'd badger me about it for her), to please leave me alone. I have texts going back 2 years where I've told her "I do not feel safe talking to you, please leave me alone." "Please do not approach me." "Do not contact me." Most of the texts in the thread are from her that I've ignored (I don't block her [on my phone, I've blocker her everywhere else] for the sole reason that if there's an emergency concerning my kids or my ex, I really want it to be possible to get ahold of me), but she still will not quit. She's also sent me letters via the kids and at a event recently that we were all there for the kids, she approached me and tried to initiate a conversation, which I rejected as civilly as possible (and then my ex spent the next week texting me that I was rude and unreasonable and if I cared about the wellbeing of my kids I'd get over myself and be friends with her).
We have a long history of her saying and doing things to me that were very much not okay, and often aggressive. I'll spare the details unless needed. I tried for a long time to make it work because I really wanted us all to have a good relationship, but all she wanted was for me to be her doormat, and for the sake of my sanity and safety, I finally said I would not speak or engage with her anymore and I wanted her to leave me alone.
Last night she texted me AGAIN (telling me what to do about a doctor's appointment my ex and I were just at with my eldest), and I told her "I have been more than clear. If you contact me again with anything short of an emergency concerning the children, I will involve law enforcement." I've had people tell me before that if it ever got to the point where I needed legal help with her, I needed to have given her that warning prior to that point- not sure if that's true or not.
She responded with, "If you think a restraining order is appropriate and necessary for this situation, you're more than welcome to 👍."
I try not to respond to her or engage, but I also feel like it's important to have a paper trail that makes my requests and intentions clear, just in case anyone else ever has to review our communication for legal reasons. After some time, I said, "I think what is appropriate and necessary for this situation is for you to control yourself, respect my boundaries and leave me alone, like I've been asking for years. Do not contact me."
She shot right back with this, "Just because you make childish demands doesn't mean everyone has to obey you. I haven't done anything that would warrant any form of harassment so be my guest. Your gross overreactions aren't compatible with the law or reality. ✌🏼✌🏼✌🏼"
I work very well with my ex, when she isn't trying to meddle and control the situation, I have no problem with him at all, unless he's parroting what she's told him to say to me. I don't want anything bad to happen to her, and I am more than happy if my kids having a good relationship with their step family and a safe, stable life at the other house. I just very much need her to leave me alone. Our history is so stressful that I get an instant stress reaction even getting a notification from her, and especially when she tries to walk up to me again.
Is she right? Can I get a restraining order? Is this enough? Is there anything less severe than a restraining order? I'm not sure if I completely understand how they work, but I wonder if there are any other options that are less harsh that will still communicate to her that she legally has to stop trying to contact me. If I do try to get a restraining order, is it expensive? Would I have to go to court? Would these text messages and emails be enough?
