i really appreciate the answers from zencow especially opesa. You guys have made me feel better. Iam relieved that this kind of disorder can be treated. but how can i get him to go see a doctor? Also i am worried because hes asking me to forget the guy personality? im afraid to answer for he might stay like that forever, i am so afraid i dont want to answer his questions anymore. what will happen?if i answered will he stay that side of his personality for life?

To Opesa, when i first read your reply everything i was relieved. Its like seeing a light at the end of a dark tunnel. Im really relieved that this symptom can be treated. I just hope that he contacts me soon because i think he chose to avoid me so we just dont argue. I want to be there for him.
And to Honeyface, thank you also. I think i need to know or talk to someone like you who have love ones with this disorder. I really wanted to help him but seems he doesnt want or just confused himself.
Thanks so much guys..i know i need to be strong.

This is way over my head, so I can only give you the only rational advice: Take him to a family doctor.

Dissociative Personality Disorder (used to be known as Multiple Personality Disorder) could be physically based, so a doctor's checkup is definitely a must. If there's nothing wrong with him physically, then he should be referred to a psychiatrist or a psychologist. The recovery rate for DPD nowadays is pretty good, so don't give up on him just yet.

Good luck
