Howdy, Jamie! I/We don't know if i'm/we're a singlet or a system yet, but I/we have been doing a lot of research into OSDD.

Here are some tips I/we recommend.

• Like all relationships, review your boundaries with them. Ask them which parts of the system are comfortable being in a relationship with you. Ask them which alters are comfortable meeting you and/or talking to you.

• Be super affirming of their experiences. A big problem with a lot of people with OSDD is doubt, so they might require an extra bit of affirmation at times.

• You mentioned they are still in the situation? Please, try your best to get them the hell out of there. If that's not possible, try to help them stay as safe as they can, and be there for them when they're dealing with the after-effects of traumatic events.

• Research, research, research. This part is fairly optional, but it's a really good idea to research into the experiences of people with OSDD to try and understand their experiences.

Hope this helped!

My advice to you is simple: treat them like multiple people. Even though they share a body, they're just as separate as if they had their own bodies. Get to know each headmate separately, and respect their boundaries. And, most importantly, ask your partner what you can do to help. They'll be able to tell you how to help better than anyone on the internet can. I wish you and your partner the best of luck!
