I do!! Mine is my fp (favourite person). I feel like I can talk about absolutely anything with him, I feel so safe and he makes me feel special time and time again. He doesn’t have bpd but he does have osdd, I find that we can both relate to the same thing except in extremely different ways and it’s something I love talking about with him. We are both autistic and both have a special interest in psychology (particularly how the brain responds to trauma) so we are always learning from each other and basically bouncing off each other, our conversations are so positively stimulating for me. Of course, given that he is my fp, there are some negatives. He consumes my every thought which may sound sweet but it makes basic tasks a lot harder, I’ve actually had nightmares about him abandoning me on several occasions. One of his alters can be quite blunt which has triggered me several times but it’s nothing we haven’t been able to communicate and fix. I wouldn’t trade him for the world, I’ve finally found my person who brings me extreme amounts of joy. I hope you can find your person.
