Hi
Don't be sorry for posting. We're here to support each other

I'm sorry about all that you've been through. Maybe give your friend some space and time. After 4 years he may simply be tired. He may just feel overwhelmed. I'm glad a couple of your friends seem willing to listen

. And the guy you like, I'm sorry he said that. It can really hurt when someone you care about doesn't seem to care about what you have to say. Maybe this is a sign he's not the right guy. You deserve someone who cares about you and is willing to listen and support you and your alters.
And remember, this isn't your fault. Nor should any of your alters feel like it's theirs. Your friend is having trouble dealing with this right now. That doesn't mean he's gone forever. It just means he needs some space and time to think. Also, remember that your friends aren't therapists. They haven't been trained to deal with DID. Even therapists get tired and stressed from their job.
