I dont know who can help, I live in Canada and there is no local Imam, If i go and talk to a family specialist or somebody and tell them how everything happenned they will right the way deport him and charge him with a criminal act for pushing me to the wall and threatening me when I was pregnant , I have a son who will turn 3 and I am extremely scared of making the wrong decision because everybody in my family will blame me and say that I had to stay in this marriage for my son and be patient have sabr that my husband might change and improve and understand his mistakes.
This part is not true. If you talk to a professional (such as a: social worker, marriage counselor, psychologist, doctor) who is bound by confidentiality, they will not get your husband arrested or deported - unless there are exceptional circumstances such as if your husband made clear threats to kill/harm you or your son. They might get the Child Protection Services involved IF they believe that there are reasonable grounds to suspect that your son may have been abused or neglected by your husband. But based on the story so far, it doesn't sound like this is the case. Therefore, there are no reasons for you to be scared or worried about approaching a counselor, such as a social worker or your family doctor, to start a discussion on the matter.
I think that you are at the point where it might in fact be quite beneficial for you to talk to an unbiased, professional counselor who will help you balance the pros and the cons of your current marriage situation without trying to guilt you into either hastily divorcing or staying in a non-functional marriage.
If you have a sister or brother that you are close to (or one parent who is more understanding than the other), maybe you want to start a discussion on the matter with them in private.
In the meantime, you can check out this Muslim Women helpline:
https://nisahelpline.com/. The toll-free number, 1-866-315 NISA (1-866-315-6472), is accessible anywhere in North America, 12 hours a day, 7 days a week. There was an article in a Canadian newspaper on this helpline a couple years ago (
https://www.thestar.com/news/gta/2012/11/15/new_helpline_for_muslim_women_may_be_canadas_first.html). I don't know what this helpline is worth, but it doesn't hurt to call, does it? If you are living in Ontario and want to better understand your legal rights in Ontario/Canada and see how these laws relate to Islamic family law, you can check out this website:

Help is available, but you need to find out for yourself what may be helpful to your situation and what isn't. Maybe talking to your parents will not help a lot (but then, who knows? Maybe your father will be very displeased to learn about what has been going on and will talk some sense into his brother). But you don't know what helps if you don't try.
Last but not least, I sincerely wish you best of luck in resolving your situation and finding appropriate help. Do your best to stay calm and to not let your husband's bad words and emotional blackmailing affect you because the more you let it show that it affects you, the more he will continue.
