You have good faith marriage. Based on your words right now if you tell
the same to a CIS official after you divorce I can tell you upfront
that you won't be approved through the I-360 form of violence against
women act VAWA.
You need the following to be approved under I-360:
Good faith marriage: you have a son so you are fine, just save common
bills and common financial responsibility between you and your spouse
at a friends house, make lots of copies.
Battery or extreme hardship caused by your spouse: you don't seem to
have that, verbal arguments are nothing, he didn't go with another
woman, he didn't hit you, he didn't lock the door on you and caused you
to be depressed, you didn't seek shelter, you didn't seek depression
treatment, you didn't file a police report or a protective order, your
spouse wansn't on drugs or alcohol 80% of the time;
or was it? any of the above? actually you might need 4 of the above
to be "OK" under vawa. so sit tight and see what is going on with your
husband and don't let the greencard metal disorder distroy your son's
life. Or do you not love him anymore? if thats the case I am afraid
your other option is to leave your son.
I am with you, just trying to help
