Adultry Advice Request

[HopeFullOfHeart]

I have been invloved with a Marine for several years. After some time he confessed that he is married to a Japanese whith whom he has a son. He keeps a house on base where he lives alone. Still they remained together to keep her from moving back to Japan & taking his son. He did not loved her, but their marrage was for the sake of their son, now he realized, a mistake.
He gave me his word that after his next deployment he would return to file for divorce.
He returned a while back and we hit a rough patch resulting from insecurities I had over the above situation. I have just found out that I am pregnant and find myself in a very very difficult situation stuck between a rock, my heart (as I love him completely, want him to be happy & want the best for him), and one very hard place. I am trying to figure out what the legal impacts given this situation might be.

#1 Should he file for divorce would his wife be able to take his son & move back to Japan? Is there any way to prevent this?

#2 Does he stand to loose his clearance, retirement and to be discharged if the command finds out?

#3 If he files for divorce would this improve the light in which his actions were viewed? (particularly if he explains his fear of her taking their son away to another country)
Sometimes things are not as black & white as they seem.
Advice is MUCH appreciated!
Thanks!

1 Should he file for divorce would his wife be able to take his son & move back to Japan? Is there any way to prevent this?
Don't know, question for family law.

#2 Does he stand to loose his clearance, retirement and to be discharged if the command finds out?
Yes, fraudulent marriage is prosecuted frequently. Also is technically adultery, conduct unbecoming, and I'm sure a few other articles as well.

#3 If he files for divorce would this improve the light in which his actions were viewed?
Probably not in the eyes of the military.
