I’m not sure what you expect people on the internet to do for you, but continuing to discuss new events about the same dysfunction isn’t helping you to resolve the situation. Action is now what is called for.
This is perhaps a good point, I think. Does there come a time when the answers have all been given, many times over, but we are still unable to make our choices or accept our reality and handle it as best we can?
The OP does keep asking similar questions when the questions needn’t be asked if the person didn’t know in their minds that the behavior was abusive or extreme.
Yes, the person she is married to is dysfunctional, and possibly to some small degree she may be also. Much advice has been given, but to continue to asking similar questions, with similar responses, can result in a failure to act on what the person already knows, or at least to accept the reality of the situation and deal with it as well as possible, especially for the sake of the child… Emotionally the responsibility can be partly shifted to the responders, who have no power of decision in the marriage, if the same issues are discussed over and over without effect. The counselling can be useful to a degree to help one cope but it also has no decision over the marriage.
Ultimately the OP has to decide whether she will continue to endure and counteract the deficient parental and spousal capacity of her husband and accept that is her lot, or she can change the situation and leave with her son, which is likely to bring with it a train of other problems. We all have things we must cope with in marriage relationships, few if any of us are all we should be. Ultimately we have to decide what we will accept as the reality of our lives and what we owe the most vulnerable persons in our relationships.
The most important person is the son who is in this marriage through no choice of his own, as an innocent child being formed by his parents and environment. Abuse is not simply physical, as we know, it also occurs when a child lacks security and consistency in the primary relationships.
No one can do other than advise the OP to stay or to leave, but she has to find the way to live the reality she chooses, with the problems that come with either decision, just as we all must, including those whose difficulties are known only within our own families.
The Serenity Prayer
cptryon.org/prayer/special/serenity.html
God grant me the serenity
to accept the things I cannot change;
courage to change the things I can;
and wisdom to know the difference.
Living one day at a time;
Enjoying one moment at a time;
Accepting hardships as the pathway to peace;
Taking, as He did, this sinful world
as it is, not as I would have it;
Trusting that He will make all things right
if I surrender to His Will;
That I may be reasonably happy in this life
and supremely happy with Him
Forever in the next.
Amen.
…
Trust in the LORD with all your heart
and lean not on your own understanding;
in all your ways acknowledge him,
and he will direct your paths.
Proverbs 3, 5-6
