Relationship problem. And all these.

I am in a relationship with my boyfriend since last two years. We are of same age and both are working. At present we are going through a tremendous problem, which we can't sort out anyway. We decided to be settled within a year but since last few months I am having a problem with the illogical interference of his mother in our relationship, his tremendous indulgence towards his sister's nuisance activities and mostly his lack of personality for which every single thing in our relationship is widely open to his family without a minimum privacy. Apart from that, he is not ready to accept any other opinion, that differs from his own opinion. At this point, both of us are suffering a lot mentally. We don't want to lose each other. But from my end it's becoming next to impossible to bear with all these. I tried to the farthest point that is possible for me. But it looks like he is unaware about my minimum disliking, liking, expectations and all these.
