Welcome to MaleSurvivor. Trying to understand a survivor and be in a relationship with one of us is truly a task. I encourage you to keep asking, keep seeking understanding for yourself in the role you wish to have as well as how he is experiencing life. "Evicting the Perpetrator" by our own Ken Singer is a good book for the survivor, "Victims No Longer" by Mike Lew is another good resource.
Be friends with him, encourage and support him as you can. Be careful not to overreach yourself, you may become discouraged o even overwhelmed. Consider joining support groups like CODA to have a physical link to this part of a relationship you wish to undertake.
Peace and comfort to you, thank you for reaching out to survivor,
