First of all I feel sorry for you. Entire happening of your life are now impacting you. So first of all be calm. As you said your husband is more in-client towards his mother and sisters, so if you also become disturb then who will take care of your kids.
It is not clear that why your husband and in-laws mentally and physically harassed you? Why you have not strongly protest all this? It is tendency of people that if other person become soft then they try to take advantage of this.Stop tolerate abuses. Strongly reply him that it is not good for educated people.Be strong.
It is some man nature that they cannot express their love and caring as women do. It does not mean that they don’t love you. So as he said it may be one of the case. You should talk to him and express all your feelings to him. Don’t be aggressive with him but calmly tell him your feelings.
Please provide more details. It will help to understand your problem. It is an open platform. Express your feelings here. This forum is like a family where we can discuss our problems.
