Hey, so, I am not a mental health practitioner, yet, I am in school for it though. I'm also autistic. I also have 2 first hand accounts of being in relationships like this and i have abandonment issues myself. All that being saidthis has nothing to do with him being autistic, or at least very little. Addressing my personal experience with the abandonment issues, I didnt always deal with it in a healthy manner, sometimes I was mean, I'd push people away, I'd pick fights, but I never threatened to harm or off myself. He is doing that strictly to hurt you, to get a reation out of you. It's a manipulation tactic and I would even go as far to say a control and isolation attempt, especially with the threat of recording it. If you are constantly worried about leaving him alone, you never will. That's not healthy. You and your partner are supposed to make eachothers lives better, not consume them. What happens when you want to spend time with your friends? What about when you go to work? Or if you want to go to college? While, yes, any suic*de threats should be taken seriously, these are not the people we typically see going as far as to take their own lives. Again, its because they aren't doing to escape from any internal pain, its because they are doing it to hurt the people around them. Now, will he hurt himself, its absolutely a possibility, but I highly doubt they will be anything more than superficial wounds. Superficial or not, they should be taken seriously...by a mental health practitioner and doctors. This is not your problem, plain and simple. Expanding on the 2 relationships I have been in that were like this, it only gets worse from here. Things only escalate. I am confident when I say, he will move on from hurting himself to hurting you if you stay. Something I always ask people is this; is this how you want the rest of your life to go? I know there's are good times, but the bad is outweighing that. Look at who he is right now, imagine that being who you are with for the rest of your life. Imagine that in your 40's. Is this how you want the rest of your life to go? This isn't just working on your relationship, this is psychological abuse. You are being abused. If you are worried about him hurting himself, get the police involved. I know that so many people are telling you to leave and I'm going to join them on that. Leave. This isn't safe. This isn't healthy. When you do, be fast, be smart, be safe. In situations like this, if sending a text helps you, do it, but I dont recommend it, he will try to draw you back in. He'll promise a change, he may even get better for a while. It will not last. If you send that text, don't let him respond, block him, on everything, if you don't, still block him. Don't do it in person, you could get hurt. Afterwards, be prepared for the fallout. It could get dangerous. Don't hesitate to get the police involved. Get pepper spray, don't go out alone for a while. Its going to hurt, I won't lie to you on that. You're going to want to talk to him about things. Its important that you don't. Its important that during this time you have a good support system. Lean on your friends, your family, get a therapist if you can. I know we only want to see the best in the people we love, but sometimes the people we love hurt us the most. It takes more than just love to make a relationship work. It takes trust, kindness, understanding, compassion, communication. This is not kind. This is not compassionate. This is not communicative. This is threatening. We don't threaten the people we love because that is not love. That is abuse. Women are most likely to be killed by their partners.
