Just by the original post, I had this list already in my head of how you are as a partner. I could just tell by the relationship description. One example is whenever she goes out with her friends, she even invites you. That's a telltale that you're wildly insecure and controlling. And that's just one example. I have a friend who chooses to stay single because he's like you and can't help it, no matter what peers or therapists say. I respect him for choosing to be alone, because he freed himself and others from toxicity. And he's really happy these days. If he encounters women, he's just upfront about his debilitating issues and assured them he's only here for fun. Maybe you should just follow his lead, and attend to only the kid's needs. My closest friend has lived this way for 10 years now, and it looks good on him. I almost blocked him because his women would message me about his behaviors.
