Marital problems

Q: Because my husband totally owns the house we live in for 34 years, does that mean according to Islam that I cannot invite my son and his family from a previous marriage to visit us or spend a night with us. Please help me here, I was told that it is my husband's house and he has the right to refuse them, but his family and friends have the right to visit and stay. That since it is his house, and even though we are married, have 2 kids, that he has the right to tell me that I can leave his house. Please advise me, this us causing me much depression.
