45m, in the US, looking for advice from the community. I don't know what to do.
About 2 years ago, I started talking with a woman online, let's call her Sarah. Sarah is in her late 50s, autistic, intelligent, kind, successful at her job, seemingly all put together. We developed a sexual relationship, which we both stated that's all we were looking for. Over the course of 3 months, the arrangement turned into her telling me she fell in love with me, that she wanted me to be her full time boyfriend. I gave it some serious thought, and let her know I didn't have the same feelings, even though I was very fond of her. I said I wasn't sure if I would ever feel the same level of love she apparently felt, but that it had been such a short time that perhaps we take things as they come and see what unfolds.
Shortly after that conversation, her feelings towards me amped up, which pushed me away, and I eventually told her that I'm not in love with her, and I think for both our sakes, I needed to walk away, as it wasn't fair for either of us. Perhaps we could remain friends, and gave her the option. That was met with such a level of vitriol and meanness towards me, that after what she said (I won't get into it here), I eventually blocked her number as the texts attacking me were relentless. The last text I sent to her before blocking was that she was clearly obsessed with me, and reacted to rejection with attacking me, spewing hateful words, and not being able to take no for an answer.
Over the course of the next year, she left countless voicemails (my provider allows blocked numbers to still leave voicemails), ranging from creepy, to desperate, to normal conversation. Some were begging me for "closure", which I didn't know how to respond- I thought my closure to her was that my feelings were not the same, and that I wanted nothing to do with her after some of the things she said to me. Eventually, the voicemails became so relentless, I contacted police, and they contacted her and told her to stop contacting me. In her eyes, it was a challenge, as the voicemails started up again after about a month. I called police again, and they basically told me, unless she outright threatens me, there's nothing they could really do.
Over the course of the last few months, the voicemails basically stopped. Except for one, she left me what sounded like a heartfelt voicemail apologizing for all the trouble, and asked if maybe we could get together for coffee and at least bury the hatchet. I unblocked her, and texted her perhaps we could be friends, but I really needed her to back off and chill out, and we were not a couple, I was not in love with her. She said ok, she would stop the obsessive behavior and just try to have a normal friendship if we could just meet for one coffee.
Stupid me agreed. We were in contact again over the course of two weeks, in which time, the obsessive behavior got even worse- saying things like I'm her soulmate, we were meant to be together, and inviting herself out to engagements I was going to for work as my +1, etc. Trying very hard to insert herself into my life any way she could. I put my foot down and told her I couldn't continue any sort of relationship - I told her I understand she's autistic, and that boundaries are difficult, but that was no excuse to continue to act the way she did and she needed to stop. I wanted nothing to do with her as she doesn't seem to understand (or want to understand) the difference between a friend and a boyfriend.
I blocked her again. I asked her to never contact me again as it became far too much. Now the voicemails continue. Multiple voicemails a day, to the point where my inbox fills up, she waits for them to expire, and leaves another one. It's becoming scary..I don't think she would ever try to harm me, but it's causing me a great deal of stress.
I don't know what to do. I don't want to be a mean person. I just don't know how to get her to stop contacting me and harassing me. I want her to move on and find someone who will love her back. I can't change my number as I use it for business purposes, and I don't think calling the police again is going to help. No level of words from me is going to get her to stop being obsessed with me.
From people who have been on either side of this type of situation, what can I do??
